Sodium bicarbonate (NaHCO?) (Sodium Bicarbonate), small white crystals, solubility in water of less than sodium carbonate. Is an industrial chemical, there may be toxic. Solid above 50 ℃ began to decompose to generate sodium carbonate, carbon dioxide and water, while 440 ℃ completely decomposed. Sodium hydrogen carbonate is an acid salt of a strong base with a weak acid is generated after neutralization, a weak alkaline when dissolved in water. This feature allows it to be used as food production process of leavening agent. Sodium bicarbonate, sodium carbonate will be left after the action, using too much can make the finished product has a base flavor.
