Ammonium Chloride

Molecular Formula

The chemical formula of the ammonium chloride is NH4Cl. It has consists of four hydrogen and one chloride ions.

How the Ammonium Chloride is Prepared

By using the solvay process it can be prepared easily. The ammonia is reacted with the hydrogen chloride or hydrochloric acid to form the ammonium chloride. It is mainly used to manufacturing the fertilizers for the plant growth. The crystals are directly deposited at the gasesous state and it should be short lived and then easily dissolved in the water. The chemical reaction is given as follows.
