NaHCO3’s full name is Sodium bicarbonate, its chemical formula is NaHCO3, which is commonly known as baking soda. It is a white fine crystals with less solubility in water than sodium carbonate. Sodium carbonate is also an industrial chemical product .The solid of sodium bicarbonate begins to decompose when temperature reaches 50 Centi degree,then it will decompose into sodium carbonate,carbon dioxide and water.
Sodium bicarbonate is an acid salt formed by neutralization of a strong base and a weak acid . When it is dissolved in water ,it becomes a weakly alkaline.WIth such a weakly alkaline,it can be used as leavening agent in the making process on foods. There will remain some basic taste of sodium carbonate if using too much.
