Sodium bicarbonate, chemical formula NaHCO? Commonly known as baking soda. White fine crystal, more insoluble in water than sodium carbonate. It is also an industrial chemical. Solids above 50℃ begin to decompose gradually to produce sodium carbonate, carbon dioxide and water, and completely decompose at 270℃.

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.
