What Is Ammonium Carbonate?
Ammonium carbonate, an ammonium salt of carbonic acid with the formula (NH4)2CO3, is known only in its monohydrate form. It is commercially produced through the sublimation of a heated mixture of calcium carbonate and ammonium sulfate, resulting in a compound salt of ammonium hydrogen carbonate and ammonium carbamate.
Uses of Ammonium Carbonate
Used in the manufacture of various ammonium salts, as an analytical reagent, and in pharmaceuticals, ammonium carbonate serves diverse roles. Traditionally known as baker’s ammonia, it has applications in baking, as well as in creating foaming agents and adhesives.
Properties of Ammonium Carbonate
With a CAS No. of 506-87-6, ammonium carbonate appears as a white, crystalline powder with a characteristic ammonia odor. Soluble in water and basic in aqueous solutions, it decomposes upon heating to produce carbon monoxide, carbon dioxide, and ammonia.
