Catalog Number
ACMA00014295
Product Name
Ammonium Bicarbonate
Description
Ammonium bicarbonate appears as a white crystalline solid having the odor of ammonia. Soluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit spread to the environment. Used to make other ammonium compounds, in food processing, and for other uses.;DryPowder; Liquid;White crystals or crystalline powder;COLOURLESS OR WHITE CRYSTALS WITH CHARACTERISTIC ODOUR.
