Product details
Property:
Colorless cubic crystal or white crystal. Salty, cool and micro-bitter. Relative density of 1.527. Sublimating when heated to 350 . Boiling point of 520 . Easily soluble in water, soluble in liquid ammonia, slightly soluble in alcohol, insoluble in acetone and ethyl ether. It starts volatilizing remarkably when heated to 100 , gets dissociated ammonia and hydrogen chloride at temp of 337.8 , and is recombinated by cold into white fog of tiny ammonium chloride, which is not easy to sink and dissolve in water. Despite small hygroscopicity, it can agglomerate as a result of moisture absorption in wet weather. Its aqueous solution is acidulous, acidity increased in heating.
