The chemical name of baking soda is sodium bicarbonate NaHCO. Sodium bicarbonate is an acid salt formed by neutralization of strong alkali and weak acid, which is weakly alkaline when dissolved in water. This characteristic can make it a leavening agent in food production. Sodium carbonate will remain after the action of sodium bicarbonate, and excessive use will make the finished product have an alkaline taste.

Extended data:
Sodium bicarbonate is a white crystal or a fine crystal of opaque monoclinic system. The specific gravity is 2. 15. Odorless, nontoxic, salty, soluble in water and slightly soluble in ethanol.
It is soluble in 10 part of water at 25℃ and 12 part of water at about 18℃. Its aqueous solution is slightly alkaline due to hydrolysis, stable at room temperature, easily decomposed when heated, gradually decomposed above 50℃, completely lost carbon dioxide at 270℃, unchanged in dry air, and slowly deliquesced in humid air.
