PHYSICAL AND CHEMICAL PROPERTIES:
Ammonium chloride, is generally found in form of  solid white crystals.It is commercially prepared by reacting  ammonia with hydrogen chloride.It also occurs naturally near volcanic regions. It dissolves itself very well in water and glycerol and is slightly soluble in alcohol.It has a saline taste.It is an acid forming salt with its aqueous solution mild acidic.It is a proper deliquescent agent and is somewhat hygroscopic in nature.It undergoes sublimation on heating .

SYNONYMS : Sal ammoniac , Ammonium muriate, Sal armagnac,Sal armoniack ,Salmiac, Nushadir salt

FORMULA :  NH4Cl 

USES : Ammonium chloride is the main component of the little dry cell batteries which is used in our daily life.It acts as an auxiliary in refining metal.It is used in photochemistry.It is also extensively employed as a constituent in galvanizing, tinning, and soldering fluxes to remove oxide coatings from metals and thereby improve the adhesion of the solders.It acts as a flavour additive in the food industry and also works as a nutrition in yeast . It also has the capability of lowering the melting temperature of certain metals which is used for certain manufacturing process . Its field of application  makes it use as an active ingredient in feed supplement for cattle,in textile printing,in cleaning products and in glues.Cosmetically, it is used in personal care products,basically in hair shampoos.Its improved quality also makes it use in snow treatment to harden the snow on ski slopes and slower  its melting.It is found in solid  blocks at the hardware shops.It also works in corroding many metals and metal oxides such as iron,copper,nickel,zinc and alluminium.It also involves itself in  etching solutions, cleaners, fertilizer and as an anti-caking agent .
