Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate), commonly known as baking soda, is a chemical compound with the formula NaHCO3. It is a salt composed of a sodium cation (Na+) and a bicarbonate anion (HCO3−). Sodium bicarbonate is a white solid that is crystalline, but often appears as a fine powder. It has a slightly salty, alkaline taste resembling that of washing soda (sodium carbonate). The natural mineral form is nahcolite. It is a component of the mineral natron and is found dissolved in many mineral springs.

Because it has long been known and is widely used, the salt has many related names such as baking soda, bread soda, cooking soda, and bicarbonate of soda. The term baking soda is more common in the United States, whereas bicarbonate of soda is more common in Australia and Britain. In colloquial usage, the names sodium bicarbonate and bicarbonate of soda are often truncated; forms such as sodium bicarb, bicarb soda, bicarbonate, and bicarb are common.
It is known as one of the E number food additives E500.
The prefix bi in bicarbonate comes from an outdated naming system and is based on the observation that there is twice as much carbonate (CO3) per sodium in sodium bicarbonate (NaHCO3) as there is in sodium carbonate (Na2CO3). The modern chemical formulas of these compounds express their precise chemical compositions (which were unknown when the names sodium carbonate and sodium bicarbonate were coined) as sodium hydrogen carbonate (NaHCO3) and sodium carbonate (Na2CO3). These names are unambiguous since sodium always has the +1 oxidation state and carbonate the -2 oxidation state.
In cooking, baking soda is primarily used in baking as a leavening agent. When it reacts with acid, carbon dioxide is released, which causes expansion of the batter and forms the characteristic texture and grain in pancakes, cakes, quick breads, soda bread, and other baked and fried foods. Acidic compounds that induce this reaction include phosphates, cream of tartar, lemon juice, yogurt, buttermilk, cocoa, and vinegar. Baking soda may be used together with sourdough, which is acidic, making a lighter product with a less acidic taste.
Heat can also by itself cause sodium bicarbonate to act as a raising agent in baking because of thermal decomposition, releasing carbon dioxide. When used this way on its own, without the presence of an acidic component (whether in the batter or by the use of a baking powder containing acid), only half the available CO2 is released. Additionally, in the absence of acid, thermal decomposition of sodium bicarbonate also produces sodium carbonate, which is strongly alkaline and gives the baked product a bitter, "soapy" taste and a yellow color.
Carbon dioxide production from exposure to heat starts at temperatures above 80 °C (180 °F).
Since the reaction occurs slowly at room temperature, mixtures (cake batter, etc.) can be allowed to stand without rising until they are heated in the oven.
Baking powder, also sold for cooking, contains around 30% of bicarbonate, and various acidic ingredients which are activated by the addition of water, without the need for additional acids in the cooking medium. Many forms of baking powder contain sodium bicarbonate combined with calcium acid phosphate, sodium aluminium phosphate, or cream of tartar. Baking soda is alkaline; the acid used in baking powder avoids a metallic taste when the chemical change during baking creates sodium carbonate.
Sodium bicarbonate was sometimes used in cooking green vegetables, as it gives them a bright green colour—which has been described as artificial-looking—due to its reacting with chlorophyll to produce chlorophyllin. However, this tends to affect taste, texture and nutritional content, and is no longer common.
Baking soda is still used to soften pulses (peas, beans) before and during cooking, as in the traditional British mushy peas recipe for soaking the peas. The main effect of sodium bicarbonate is to modify the pH of the soaking solution and cooking water, that in turn softens the hard external shell, reduces cooking times and may alter the percentage of nutrients in the dish, its flavour and consistence.
Baking soda may react with acids in food, including vitamin C (L-ascorbic acid).
It is used in Asian and Latin American cuisine to tenderize meats. It is also used in breading, such as for fried foods, to enhance crispness and allow passages for steam to escape, so the breading is not blown off during cooking.
Sodium bicarbonate can be administered to pools, spas, and garden ponds to raise the total alkalinity. This will also raise the pH level and make maintaining proper pH easier. In the event that the pH is high, sodium bicarbonate should not be used to adjust the pH.
Sodium bicarbonate is one of the main components of the common "black snake" firework. The effect is caused by the thermal decomposition, which produces carbon dioxide gas to produce a long snake-like ash as a combustion product of the other main component, sucrose.
It has weak disinfectant properties, and it may be an effective fungicide against some organisms. Because baking soda will absorb musty smells, it has become a reliable method for used book sellers when making books less malodorous.
Sodium bicarbonate can be used to extinguish small grease or electrical fires by being thrown over the fire, as heating of sodium bicarbonate releases carbon dioxide. However, it should not be applied to fires in deep fryers; the sudden release of gas may cause the grease to splatter. Sodium bicarbonate is used in BC dry chemical fire extinguishers as an alternative to the more corrosive diammonium phosphate in ABC extinguishers. The alkaline nature of sodium bicarbonate makes it the only dry chemical agent, besides Purple-K, that was used in large-scale fire suppression systems installed in commercial kitchens. Because it can act as an alkali, the agent has a mild saponification effect on hot grease, which forms a smothering, soapy foam.
Sodium bicarbonate reacts spontaneously with acids, releasing CO2 gas as a reaction product. It is commonly used to neutralize unwanted acid solutions or acid spills in chemical laboratories. It is not appropriate to use sodium bicarbonate to neutralize base even though it is amphoteric, reacting with both acids and bases.
A mixture of sodium bicarbonate and polyethylene glycol such as PegLyte, dissolved in water and taken orally, is an effective gastrointestinal lavage preparation and laxative prior to gastrointestinal surgery, gastroscopy, etc.
Intravenous sodium bicarbonate in an aqueous solution is sometimes used for cases of acidosis, or when insufficient sodium or bicarbonate ions are in the blood. In cases of respiratory acidosis, the infused bicarbonate ion drives the carbonic acid/bicarbonate buffer of plasma to the left, and thus raises the pH. For this reason, sodium bicarbonate is used in medically supervised cardiopulmonary resuscitation. Infusion of bicarbonate is indicated only when the blood pH is markedly low (< 7.1–7.0).
HCO3− is used for treatment of hyperkalemia, as it will drive K+ back into cells during periods of acidosis. Since sodium bicarbonate can cause alkalosis, it is sometimes used to treat aspirin overdoses. Aspirin requires an acidic environment for proper absorption, and the basic environment diminishes aspirin absorption in the case of an overdose. Sodium bicarbonate has also been used in the treatment of tricyclic antidepressant overdose. It can also be applied topically as a paste, with three parts baking soda to one part water, to relieve some kinds of insect bites and stings (as well as accompanying swelling).
Some alternative practitioners, such as Tullio Simoncini, have promoted baking soda as a cancer cure, which the American Cancer Society has warned against due to both its unproven effectiveness and potential danger in use. Edzard Ernst has called the promotion of sodium bicarbonate as a cancer cure "one of the more sickening alternative cancer scams I have seen for a long time".
Sodium bicarbonate can be added to local anesthetics, to speed up the onset of their effects and make their injection less painful. It is also a component of Moffett's solution, used in nasal surgery.
As early as the 1920s, bicarbonate was found to cause increased bone strength in patients who were losing calcium in their urine. In 1968, diets producing too much acid were thought to put bones at risk. Experiments by Anthony Sebastian of the University of California, San Francisco starting in the late 20th century found that the body was breaking down bones and muscles to release carbonates, phosphates, and ammonia, which neutralize acid. Adding bicarbonate to the diet (he chose to use the sodium-free saleratus, potassium bicarbonate) reduced loss of calcium in postmenopausal women, amounting to the equivalent of "an arm-and-a-leg's worth" of bone if this continued for two decades.
Similarly to its use in baking, sodium bicarbonate is used together with a mild acid such as tartaric acid as the excipient in effervescent tablets: when such a tablet is dropped in a glass of water, the carbonate leaves the reaction medium as carbon dioxide gas ( HCO3− + H+ → H2O + CO2↑ or, more precisely, HCO3− + H3O+ → 2 H2O + CO2↑ ) leaving the medication dissolved in the water together with the resulting salt (in this example, sodium tartrate).
Sodium bicarbonate is also used as an ingredient in some mouthwashes. It has anticaries and abrasive properties. It works as a mechanical cleanser on the teeth and gums, neutralizes the production of acid in the mouth, and also acts as an antiseptic to help prevent infections. Sodium bicarbonate in combination with other ingredients can be used to make a dry or wet deodorant. Sodium bicarbonate may be used as a buffering agent, combined with table salt, when creating a solution for nasal irrigation.
It is used in eye hygiene to treat blepharitis. This is done by addition of a teaspoon of sodium bicarbonate to cool water that was recently boiled, followed by gentle scrubbing of the eyelash base with a cotton swab dipped in the solution.
Small amounts of sodium bicarbonate have been shown to be useful as a supplement for athletes in speed-based events, such as middle-distance running, lasting about 1–7 minutes. However, overdose is a serious risk because sodium bicarbonate is slightly toxic; and gastrointestinal irritation is of particular concern. Additionally, this practice causes an increase in dietary sodium.
Sodium bicarbonate is used in a process for removing paint and corrosion called sodablasting; the process is particularly suitable for cleaning aluminium panels which can be distorted by other types of abrasives.
A manufacturer recommends a paste made from baking soda with minimal water as a gentle scouring powder, and is useful in removing surface rust, as the rust forms a water-soluble compound when in a concentrated alkaline solution; cold water should be used, as hot-water solutions can corrode steel.  Sodium bicarbonate attacks the thin protective oxide layer that forms on aluminium, making it unsuitable for cleaning this metal. A solution in warm water will remove the tarnish from silver when the silver is in contact with a piece of aluminium foil. Baking soda is commonly added to washing machines as a replacement for water softener and to remove odors from clothes. It is also effective in removing heavy tea and coffee stains from cups when diluted with warm water. Also, baking soda can be used as a multipurpose odor remover.
During the Manhattan Project to develop the nuclear bomb in the early 1940s, the chemical toxicity of uranium was an issue. Uranium oxides were found to stick very well to cotton cloth, and did not wash out with soap or laundry detergent. However, the uranium would wash out with a 2% solution of sodium bicarbonate. Clothing can become contaminated with toxic dust of depleted uranium (DU), which is very dense, hence used for counterweights in a civilian context, and in armour-piercing projectiles. DU is not removed by normal laundering; washing with about 6 ounces (170 g) of baking soda in 2 gallons (7.5 l) of water will help to wash it out.
Sodium bicarbonate can be used as a wash to remove any acidic impurities from a "crude" liquid, producing a purer sample. Reaction of sodium bicarbonate and an acid produces a salt and carbonic acid, which readily decomposes to carbon dioxide and water:
Sodium bicarbonate reacts with bases such as sodium hydroxide to form carbonates:
Above 50 °C (122 °F), sodium bicarbonate gradually decomposes into sodium carbonate, water, and carbon dioxide. The conversion is fast at 200 °C (392 °F):
These conversions are relevant to the use of NaHCO3 as a fire-suppression agent ("BC powder") in some dry-powder fire extinguishers.
In 1791, French chemist Nicolas Leblanc produced sodium carbonate, also known as soda ash. In 1846, two New York bakers, John Dwight and Austin Church, established the first factory in the United States to produce baking soda from sodium carbonate and carbon dioxide.
Saleratus, potassium or sodium bicarbonate, is mentioned in the novel Captains Courageous by Rudyard Kipling as being used extensively in the 1800s in commercial fishing to prevent freshly caught fish from spoiling.
It is produced on the scale of about 100,000 tonnes/year (as of 2001). Commercial quantities of baking soda are also produced by a similar method: soda ash, mined in the form of the ore trona, is dissolved in water and treated with carbon dioxide. Sodium bicarbonate precipitates as a solid from this solution.
Although of no practical value, NaHCO3 may be obtained by the reaction of carbon dioxide with an aqueous solution of sodium hydroxide:
Naturally occurring deposits of nahcolite (NaHCO3) are found in the Eocene-age (55.8–33.9 Mya) Green River Formation, Piceance Basin in Colorado. Nahcolite was deposited as beds during periods of high evaporation in the basin. It is commercially mined using common underground mining techniques such as bore, drum, and longwall mining in a fashion very similar to coal mining.
Limited amounts of product are further obtained by solution mining, pumping heated water through previously mined nahcolite beds and reconstituting the dissolved nahcolite above ground through a natural cooling crystallization process. Currently, only Genesis Alkali (formerly Tronox, formerly FMC) in the Green River Wyoming basin has successfully commercially solution mined the product.
Sodium bicarbonate, as "bicarbonate of soda", was a frequent source of punch lines for Groucho Marx in Marx brothers movies. In Duck Soup, Marx plays the leader of a nation at war. In one scene, he receives a message from the battlefield that his general is reporting a gas attack, and Groucho tells his aide: "Tell him to take a teaspoonful of bicarbonate of soda and a half a glass of water." In A Night at the Opera, Groucho's character addresses the opening night crowd at an opera by saying of the lead tenor: "Signor Lassparri comes from a very famous family. His mother was a well-known bass singer. His father was the first man to stuff spaghetti with bicarbonate of soda, thus causing and curing indigestion at the same time."
In a nutshell, the uses for baking soda are many: It deodorizes, neutralizes, and cleans all without the toxic mess of most commercial products.
Consuming sodium bicarbonate can also raise your blood sodium levels, which may increase blood pressure in some people.
Alka-Seltzer is an effervescent antacid and pain reliever first marketed by the Dr. Miles Medicine Company of Elkhart, Indiana, United States. Alka-Seltzer contains three active ingredients: aspirin (acetylsalicylic acid) (ASA), sodium bicarbonate, and anhydrous
citric acid. The aspirin is a pain reliever and anti-inflammatory, the sodium bicarbonate is an antacid, and the citric acid reacts with the sodium bicarbonate and water to form effervescence.It was developed by head chemist Maurice Treneer. Alka-Seltzer is marketed for relief of minor aches, pains, inflammation, fever, headache, heartburn, stomachache, indigestion, acid reflux and hangovers, while neutralizing excess stomach acid. It was launched in 1931.Its sister product, Alka-Seltzer Plus, treats cold and flu symptoms.Baking powder
Baking powder is a dry chemical leavening agent, a mixture of a carbonate or bicarbonate and a weak acid. The base and acid are prevented from reacting prematurely by the inclusion of a buffer such as cornstarch. Baking powder is used to increase the volume and lighten the texture of baked goods. It works by releasing carbon dioxide gas into a batter or dough through an acid-base reaction, causing bubbles in the wet mixture to expand and thus leavening the mixture. The first single-acting baking powder was developed by Birmingham based food manufacturer Alfred Bird in England in 1843. The first double-acting baking powder was developed by Eben Norton Horsford in America in the 1860s.
Baking powder is used instead of yeast for end-products where fermentation flavors would be undesirable,
where the batter lacks the elastic structure to hold gas bubbles for more than a few minutes, and to speed the production of baked goods. Because carbon dioxide is released at a faster rate through the acid-base reaction than through fermentation, breads made by chemical leavening are called quick breads. The introduction of baking powder was revolutionary in minimizing the time and labor required to make breadstuffs. It led to the creation of new types of cakes, cookies, biscuits, and other baked goods.Bicarbonate
In inorganic chemistry, bicarbonate (IUPAC-recommended nomenclature: hydrogencarbonate) is an intermediate form in the deprotonation of carbonic acid. It is a polyatomic anion with the chemical formula HCO−3.
Bicarbonate serves a crucial biochemical role in the physiological pH buffering system.The term "bicarbonate" was coined in 1814 by the English chemist William Hyde Wollaston. The prefix "bi" in "bicarbonate" comes from an outdated naming system and is based on the observation that there is twice as much carbonate (CO2−3) per sodium ion in sodium bicarbonate (NaHCO3) and other bicarbonates than in sodium carbonate (Na2CO3) and other carbonates. The name lives on as a trivial name.
According to the Wikipedia article IUPAC nomenclature of inorganic chemistry, the prefix bi– is a deprecated way of indicating the presence of a single hydrogen ion. The recommended nomenclature today mandates explicit referencing of the presence of the single hydrogen ion: sodium hydrogen carbonate or sodium hydrogencarbonate. A parallel example is sodium bisulfite (NaHSO3).Black snake (firework)
Black snake and sugar snake are two similar types of firework.
After being lit, both fireworks may begin to smoke and may spew out ash resembling a snake via an intumescent reaction. They may stay on the ground and do not emit sparks, flares, any form of projectiles, or any sound, but may release smoke.
Sodium bicarbonate which produces carbon dioxide gas, and sugar forming carbon containing ash, are common chemicals used for the black snake demonstration. Other sources report the contents as "a nitrated mixture of linseed oil and naphthalenes".The traditional "Pharaoh's serpent" version of this firework produces a more impressive snake, but its operation depends upon mercury (II) thiocyanate, which is no longer commonly used because of its toxicity.Chyme
Chyme or chymus (; from Greek χυμός khymos, "juice") is the semi-fluid mass of partly digested food that is expelled by the stomach, through the pyloric valve, into the duodenum (the beginning of the small intestine).
Chyme results from the mechanical and chemical breakdown of a bolus and consists of partially digested food, water, hydrochloric acid, and various digestive enzymes. Chyme slowly passes through the pyloric sphincter and into the duodenum, where the extraction of nutrients begins. Depending on the quantity and contents of the meal, the stomach will digest the food into chyme in anywhere between 40 minutes to 3 hours at most.
With a pH of approximately 2, chyme emerging from the stomach is very acidic. The duodenum secretes a hormone, cholecystokinin (CCK), which causes the gall bladder to contract, releasing alkaline bile into the duodenum. CCK also causes the release of digestive enzymes from the pancreas. The duodenum is a short section of the small intestine located between the stomach and the rest of the small intestine. The duodenum also produces the hormone secretin to stimulate the pancreatic secretion of large amounts of sodium bicarbonate, which then raises pH of the chyme to 7. The chyme then moves through the jejunum and the ileum, where digestion progresses, and the nonuseful portion continues onward into the large intestine. The duodenum is protected by a thick layer of mucus and the neutralizing actions of the sodium bicarbonate and bile.
At a pH of 7, the enzymes that were present from the stomach are no longer active. This then leads into the further breakdown of the nutrients still present by anaerobic bacteria, which at the same time help to package the remains. These bacteria also help synthesize vitamin B and vitamin K, which will be absorbed along with other nutrients.Electrogenic sodium bicarbonate cotransporter 1
Electrogenic sodium bicarbonate cotransporter 1 is a membrane transport protein that in humans is encoded by the SLC4A4 gene.Electrogenic sodium bicarbonate cotransporter 4
Electrogenic sodium bicarbonate cotransporter 4 is a protein that in humans is encoded by the SLC4A5 gene.Electroneutral sodium bicarbonate exchanger 1
Electroneutral sodium bicarbonate exchanger 1 is a protein that in humans is encoded by the SLC4A8 gene.Eno (drug)
Eno is an over-the-counter antacid brand, produced by GlaxoSmithKline. Its main ingredients are sodium bicarbonate and citric acid.Intravenous sodium bicarbonate
Intravenous sodium bicarbonate, also known as sodium hydrogen carbonate, is a medication primarily used to treat severe metabolic acidosis. For this purpose it is generally only used when the pH is less than 7.1 and when the underlying cause is either diarrhea, vomiting, or the kidneys. Other uses include high blood potassium, tricyclic antidepressant overdose, and cocaine toxicity as well as a number of other poisonings. It is given by injection into a vein.Side effects may include low blood potassium, high blood sodium, and swelling. It is not recommended in people with low blood calcium. Sodium bicarbonate is in the alkalinizing family of medication. It works by increasing blood bicarbonate, which buffers excess hydrogen ion and raises blood pH.Commercial production of sodium bicarbonate began between 1791 and 1823. Intravenous medical use began around the 1950s. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. Sodium bicarbonate is available as a generic medication. The wholesale cost in the developing world is about US$0.09–2.58 per 10 ml of 8.4% solution. In the United Kingdom this amount costs the NHS about 11.10 pounds.Mushy peas
Mushy peas are dried marrowfat peas which are first soaked overnight in water with sodium bicarbonate (baking soda), then rinsed in fresh water, after which the peas are gathered in a saucepan, covered with water, and brought to a boil, then simmered until the peas are softened and mushy. The mush is seasoned with salt and pepper.Throughout the British Isles (Northern England and the Midlands in particular) they are a traditional accompaniment to fish and chips. In Northern England they are also commonly served as part of a popular snack called pie and peas (akin to the South Australian pie floater, but with mushy peas instead of a thick pea soup accompanying the meat pie) and are considered to be a part of traditional British cuisine. They are sometimes also packed into a ball, dipped in batter, deep-fried, and served as a pea fritter. Mushy peas can also be bought ready-prepared in tin cans.Natron
Natron is a naturally occurring mixture of sodium carbonate decahydrate (Na2CO3·10H2O, a kind of soda ash) and around 17% sodium bicarbonate (also called baking soda, NaHCO3) along with small quantities of sodium chloride and sodium sulfate. Natron is white to colourless when pure, varying to gray or yellow with impurities. Natron deposits are sometimes found in saline lake beds which arose in arid environments. Throughout history natron has had many practical applications that continue today in the wide range of modern uses of its constituent mineral components.
In modern mineralogy the term natron has come to mean only the sodium carbonate decahydrate (hydrated soda ash) that makes up most of the historical salt.Sodablasting
Sodablasting is a mild form of abrasive blasting in which sodium bicarbonate particles are blasted against a surface using compressed air. It has a much milder abrasive effect than sandblasting. An early use was in the conservation-restoration of the Statue of Liberty in the 1980s.Sodablasting is a non-destructive method for many applications in cleaning, paint and varnish stripping, automotive restoration, industrial equipment maintenance, rust removal, graffiti removal, molecular steel passivation against rust, oil removal by saponification and translocation, masonry cleaning and restoration, soot remediation, boat hull cleaning and for food processing facilities and equipment and tooth cleaning at the dental laboratory.Sodium bicarbonate cotransporter 3
Sodium bicarbonate cotransporter 3 is a protein which in humans is encoded by the SLC4A7 gene.Sodium bicarbonate rocket
A sodium bicarbonate rocket (sometimes called an Alka-Seltzer rocket) is a model rocket fashioned from a 35mm film canister and propelled by the pressure of a gas, often carbon dioxide, generated from the reaction of an acid with sodium bicarbonate. Sodium bicarbonate rockets are often used in science classes to demonstrate principles of chemistry and physics.
In the experiment, a film canister is filled with water, an effervescent tablet (commonly Alka-Seltzer) is added and the canister tightly sealed. After a short time, the pressure of the carbon dioxide is great enough to cause the body of the canister to be launched into the air with a popping sound. The canister may be embellished with paper fins to resemble more closely a real rocket.Various experiments and lessons can center around the use of a bicarbonate rocket. For example, students are sometimes asked to experiment with the amounts of water and Alka-Seltzer to find the combination which propels the rocket the greatest distance. Alternatively they may derive equations to calculate the speed and velocity of the rocket from the distance it travels.In rocketry, a chemical reaction rapidly creates gas that is expelled in one direction from its container (the rocket engine); momentum forces the rocket in the opposite direction. The alka-seltzer rocket experiment demonstrates Newton's third law. The film canister rocket has a buildup of gas that wants to come out of the weakest spot making all the gas come out at once through the hole at the bottom. The gas comes out from the underside and pushes the rocket up. After it gets pushed up, air resistance slows it down and gravity pulls it down to earth. The film canister accelerates quickly because it has very little mass.
The film canister rocket uses a solid fuel mixed with a liquid fuel to create a gas that escapes out of the bottom. The gas is carbon dioxide (CO2), the liquid is water (H2O), and the solid is an effervescent tablet. When the H2O is mixed with an effervescent tablet, it produces the gas CO2. The reaction time depends on the surface area of the tablet.Sodium bicarbonate transporter-like protein 11
Sodium bicarbonate transporter-like protein 11 is a protein that in humans is encoded by the SLC4A11 gene.Tata Chemicals Europe
Tata Chemicals Europe (formerly Brunner Mond (UK) Limited) is a UK-based chemicals company that is a subsidiary of Tata Chemicals Limited, itself a part of the India-based Tata Group. Its principal products are soda ash, sodium bicarbonate, calcium chloride and associated alkaline chemicals.Tullio Simoncini
Tullio Simoncini (born 1951) is a convicted fraudster and former Italian physician known for alternative medicine advocacy. He is known for the false claim that cancer is caused by the fungus Candida albicans, and has argued that cancer is a form of candida overgrowth. He also made the false claim that cancer can be cured with injections of sodium bicarbonate. On his website, Simoncini says that he was formerly an oncologist but that designation has been challenged by the medical community because of his use of sodium bicarbonate in the treatment of cancer.The mainstream medical community rejects Simoncini's hypothesis, citing a lack of peer-reviewed studies that support it. Quackwatch lists sodium bicarbonate injections as a "dubious treatment."ZotZ (candy)
ZotZ is a candy with a fizzy, sour center manufactured by G.B. Ambrosoli in Italy and distributed in the United States by Andre Prost, Inc. It is a hard candy that contains a sour powder comprising malic and tartaric acids mixed with sodium bicarbonate. When the powder dissolves, the acids dissolve in liquid (saliva or water) and react with the sodium bicarbonate to produce carbon dioxide bubbles and a fizzing sensation. Zotz has a mild sour flavor to it, owing to the acids involved in its ingredients.
ZotZ flavors include apple, cherry, watermelon, blue raspberry, strawberry, grape, and orange. As of 2019, they are still currently in production and sold in stores. The most common flavor is Watermelon.ZotZ is the official candy of American Endurance Racing (AER).
