and other food products. { ə mo ¯ n yəm al jə na ¯ t}


ammoniumacetate [ORG CHEM] 1. CH3COONH4 A normal salt formed by the neutraliza-
tion of acetic acid with ammonium hydroxide; a white, crystalline, deliquescent
material used in solution for the standardization of electrodes for hydrogen ions.
2. CH3COONH4 CH3COOH An acid salt resulting from the distillation of the neutral
salt or from its solution in hot acetic acid; crystallizes in deliquescent needles.
3. A mixture of the normal and acetic salts; used as a mordant in the dyeing of wool.
