Ammonium Chloride

Listing ID #3725195

Ammonium chloride, an inorganic compound with the formula NH4Cl, is a white crystalline salt, highly soluble in water. Solutions of ammonium chloride are mildly acidic. Sal ammoniac is a name of the natural, mineralogical form of ammonium chloride. The mineral is commonly formed on burning coal dumps, due to condensation of coal-derived gases. It is also found around some types of volcanic vents. It is used as a flavoring agent in some types of liquorices. It is the product from the reaction of hydrochloric acid and ammonia.
Ammonium chloride reacts with a strong base, e.g. sodium hydroxide, to release ammonia gas. Similarly, ammonium chloride also reacts with alkali metal carbonates at elevated temperatures, giving ammonia and alkali metal chloride. Some of ammonium chloride's reactions with other chemicals are endothermic, for example its reaction with barium hydroxide, and its dissolving in water.
