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.
