sodium bicarbonate (redirected from Citrocarbonate)

sodium bicarbonate or sodium hydrogen carbonate, chemical compound, NaHCO₃, a white crystalline or granular powder, commonly known as bicarbonate of soda or baking soda. It is soluble in water and very slightly soluble in alcohol. It evolves carbon dioxide gas when heated above about 50°C;, a property made use of in baking powder, of which it is a component. It is also decomposed by most acids; the acid is neutralized and carbon dioxide is given off. The major use of sodium bicarbonate is in foods, e.g., baked goods. It is used in effervescent "salts" and is sometimes used medically to correct excess stomach acidity. It is also used in several kinds of fire extinguishers. Although it is an intermediate product in the Solvay process for making sodium carbonate, it is more economical to prepare it from purified sodium carbonate than to purify the intermediate. Because the bicarbonate is less soluble than the carbonate, carbon dioxide gas is bubbled into a saturated solution of pure carbonate, and the bicarbonate precipitates out to be collected and dried.

 or sodium bicarbonate or baking soda

Inorganic compound, white, crystalline salt of sodium, chemical formula NaHCO₃. It is a weak base and dissociates into water and carbon dioxide gas as it dissolves in the presence of hydrogen ions. In addition to household uses as an antacid, cleaner, and deodorizer, it is used in manufacturing effervescent salts and beverages and baking powder. Industrial uses include production of other sodium salts, treatment of wool and silk, and use in pharmaceuticals, sponge rubber, fire extinguishers, cleaners, lab reagents, mouthwash, and gold and platinum plating.
