Sodium Bicarbonate

タイトルまたは説明

Sodium Bicarbonate, commonly called baking soda, is a white odourless, crystalline solid, completely soluble in water but slightly soluble in ethanol. It is the mildest of all sodium alkalis. It is prepared from purified sodium carbonate or sodium hydroxide solution with passing carbon dioxide which is bubbled into the solution of pure carbonate, and the bicarbonate precipitates out to be dried as the bicarbonate is less soluble than the carbonate. Sodium bicarbonate is also made as an intermediate product in the Solvay process which is to make sodium carbonate from calcium carbonate by treating sodium chloride with ammonia and carbon dioxide.
