Ammonium Chloride

It is also called Sal ammoniac, the salt of ammonia and hydrogen chloride. Its principal uses are as a nitrogen supply in fertilizers and as an electrolyte in dry cells, and it is also extensively employed as a constituent of galvanizing, tinning, and soldering fluxes to remove oxide coatings from metals and thereby improve the adhesion of the solders. Ammonium chloride is a colourless crystalline substance. It is highly soluble in water, readily forming a slightly acidic solution. It vaporizes without melting at 340 °C (644 °F) to form equal volumes of ammonia and hydrogen chloride. Ammonium chloride is yielded as a by-product in the ammonia-soda process for making sodium carbonate. Other applications for ammonium chloride include electrolyte for plating baths and/or batteries, fertilizer, personal care product formulations, pharmaceuticals, and other applications where the anticaking agent can cause problems. Ammonium Chloride is an inorganic, mildly acidic, white crystalline salt compound that is highly soluble in water.
