- Sodium bicarbonate definition: a white, crystalline, water-soluble solid, in powder or granules, NaHCO3, usually prepared by the reaction of soda ash with carbon dioxide or obtained from the intermediate product of the Solvay process by purification.
Oct 23, 2023 · When sodium bicarbonate is heated, it melts into a liquid, and when the liquid is heated further, it can vaporize into a gas. Conversely, when sodium bicarbonate is cooled, it can solidify from a liquid or a gas.

Sodium bicarbonate (SO-dee-um bye-KAR-bun-ate) is a white, odorless, crystalline solid or powder that is stable in dry air, but that slowly decomposes in moist air to form sodium carbonate. The compound's primary uses are as an additive in human and animal food products.
OTHER NAMES:
Bicarbonate of soda; baking soda

Sodium, hydrogen, carbon, oxygen
Sodium bicarbonate is made commercially by one of two methods. In the first method, carbon dioxide gas is passed through an aqueous solution of sodium carbonate (Na2CO3): Since the bicarbonate is less soluble than the carbonate, it precipitates out of solution and can be removed by filtration. Sodium bicarbonate is also obtained as a byproduct of t...
Sodium bicarbonate is a very effective cleaning agent for certain materials. In the 1980s, restorers used an aqueous solution of the compound to clean the Statue of Liberty.
An estimated 560,000 metric tons (615,000 short tons) of sodium bicarbonate were consumed in the United States in 2003. About one-third of that amount was used by the food products industry, primarily in the manufacture of baking soda (pure sodium bicarbonate) and baking powder (a mixture of sodium bicarbonate and at least one other compound). Baki...

Baking soda only contains sodium bicarbonate, also called bicarbonate of soda. There is no acidic powder to cause a reaction. Baking soda is four times stronger than baking powder, so you need less in recipes. How does Baking Soda Work? Baking soda works as a leavening agent when mixed with an acidic ingredient.
Oct 23, 2023 · Sodium bicarbonate can exist in both solid and liquid forms, depending on the temperature and pressure conditions. At room temperature and normal atmospheric pressure, sodium bicarbonate is a solid powder.
Baking soda is a white crystalline powder (NaHCO 3 ) better known to chemists as sodium bicarbonate, bicarbonate of soda, sodium hydrogen carbonate, or sodium acid carbonate. It is classified as an acid salt, formed by combining an acid (carbonic) and a base (sodium hydroxide), and it reacts with other chemicals as a mild alkali.
Mar 8, 2019 · The molecular formula of sodium bicarbonate is NaHCO 3. The compound is a salt that dissociates into sodium (Na + ) cation and carbonate (CO 3 - ) anions in water. Baking soda is an alkaline white crystalline solid, usually sold as a powder.
Nov 2, 2020 · The formula for sodium bicarbonate is NaHCO 3. There is another compound called washing soda or sodium carbonate, which has the formula Na 2 CO 3. Heating baking soda drives off the hydrogen and gives you washing soda. Dissolving baking soda yields one sodium ion and one bicarbonate anion (HCO 3 –). Dissolving washing soda gives you two ...
