Molecular weight: 84.01
Appearance: white, salty, powder or crystal.
Appearance: white powder or opaque monoclinic crystal system fine crystal. Odorless, salty. It is less soluble in water than sodium carbonate. Solids begin to decompose gradually into sodium carbonate, carbon dioxide and water above 50 ° C, and decompose completely at 270 ° C. Sodium bicarbonate is an acid salt formed after the neutralization of a strong base and a weak acid, and is weakly alkaline when dissolved in water. This property is often used as a leavening agent in food preparation. Sodium bicarbonate will remain sodium carbonate after the action, and too much use will give the finished product an alkali taste.
