Ammonium Chloride

Synonyms: Sal ammoniac; Ammonium muriate
CAS No.: 12125-02-9
Molecular Weight: 53.49
Chemical Formula: NH4Cl
Ammonium Chloride is a colorless cubic crystal or white crystalline substance with a salted and light bitter taste. The specific gravity is 1.527. It begins to vaporize without melting at 350C and boil at 520C. It is highly soluble in water, readily forming a slightly acidic solution whose acidity will be stronger. It is also soluble in liquid ammonia and slightly soluble in alcohol but not soluble in acetone and aether. It observably volatilizes when heated at 100C and dissociates into ammonia and HCl, which combine into NH4Cl again when cooling in the form of white foggy substance containing extremely small granules of NH4Cl. This substance can not precipitated and become extremely insoluble in water. It has a weak hygroscopicity but can cake due to water absorption in wet or rainy days. It corrodes black metals and other non-ferrous metals, especially copper, but it does not corrode pig iron.
