Ammonium chloride (NH4Cl) is a colorless, crystalline water-soluble substance (ammonium salt). Occurs in
nature as the mineral ammonium chloride. The easiest method for its preparation (used also priemyslene) is
the reaction of ammonia with hydrogen chloride: NH3 + HCl → NH4Cl
Ammonium chloride is, however, such action. alkali decomposes into ammonia, which escapes out of the
reaction mixture and the reaction is continuously shifted to the product and the alkali metal chloride. The
reaction is exothermic and the reaction was surging. Ammonium chloride is the starting material for the
production of other nitrogen compounds.
