description
ammonium chloride occurs as colorless crystals or as a white, fine or coarse, crystalline powder. It is somewhat hygroscopic. One gram dissolves in 2.6 ml of water at 25°, in 1.4 ml of boiling water, in about 100 ml of alcohol, and in about 8 ml of glycerin. The ph of a 1:20 solution is between 4.5 and 6.0.
Requirements
identification: a 1:10 aqueous solution gives positive tests for ammonium and for chloride.
Assay: not less than 99.0% of nh4cl after drying.
Lead: not more than 4 mgkg.
Loss on drying: not more than 0.5%.
