Ammonium Chloride

CAS #: 12125-02-9

Synonyms: Sal ammoniac; salmiac; ammonium muriate

Uses: Dry batteries, mordant (dyeing and printing), soldering flux, manufacturing of various ammonia compounds, fertilizer, pickeling agent in zinc coating and tinning, electtroplating, washing powders, melt-retarding snow treatment, production of ureaformaldehyde resins and adhesives, bakery products.

Hazard:  Inhalation of fumes irritates respiratory passages. Ingestion irritates mouth and stomach. Fumes are irritating to eyes. Contact with skin may cause irritation.  Acidic salts, such as AMMONIUM CHLORIDE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH’s of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
