Ammonium chloride (NH4Cl) is a white inorganic water soluble salt. It can be formed by reacting ammonia with hydrochloric acid. It is used as a food additive under the name sal ammoniac or the E-number E510.

In refining it is used for precipitating ammonium hexachloroplatinate from concentrated solutions of platinum chloride. Some iridium ammoniumchloride can also precipitate if the solution is left standing.
