GENERAL DESCRIPTION

Ammonium Bicarbonate, also called ammonium hydrogen carbonate, is a white, crystalline powder. It is soluble in water but non-soluble in alcohol and acetone. It decomposes at 36 to 60C to the base of ammonia, carbon dioxide and water vapor. It is used in baking powders and in fire-extinguishing mixtures. It is also used in wide industries of plastics and rubber , compounding of cleaners and polishes  and  chemical manufacturing and as a basic fertilizer and fertilizer dressing  as a source of ammonia.
