Safety Information

Ammonium chloride Usage And Synthesis

Chemical Properties	white crystalline powder
General Description	Ammonium chloride is a white crystalline solid. Ammonium chloride is soluble in water(37%). The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. Ammonium chloride is used to make other ammonium compounds, as a soldering flux, as a fertilizer, and for many other uses.
Air & Water Reactions	Soluble in water. Slowly releases hydrogen chloride [USCG, 1999].
Reactivity Profile	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.
Health Hazard	Inhalation of fumes irritates respiratory passages. Ingestion irritates mouth and stomach. Fumes are irritating to eyes. Contact with skin may cause irritation.
