Some information about the usage of ammonia. Look at the table below and try to understand the application of ammonia in daily life

INDUSTRY	USAGE
Fertilser	production of: ammonium sulfate, (NH4)2SO4 ammonium phosphate, (NH4)3PO4 ammonium nitrate, NH4NO3 urea, (NH2)2CO,also used in the production of barbiturates (sedatives), is made by the reaction of ammonia with carbon dioxide
CO2 carbon dioxide + 2NH3 ammonia H2NCOONH4 ammonium carbonate heat, pressure (NH2)2CO urea
Chemicals	synthesis of: nitric acid, HNO3, which is used in making explosives such as TNT (2,4,6-trinitrotoluene), nitroglycerine which is also used as a vasodilator (a substance that dilates blood vessels) and PETN (pentaerythritol nitrate). sodium hydrogen carbonate (sodium bicarbonate), NaHCO3 sodium carbonate, Na2CO3 hydrogen cyanide (hydrocyanic acid), HCN hydrazine, N2H4 (used in rocket propulsion systems)
Explosives	ammonium nitrate, NH4NO3
Fibres and Plastics	nylon, -[(CH2)4-CO-NH-(CH2)6-NH-CO]-,and other polyamides
Refrigeration	used for making ice, large scale refrigeration plants, air-conditioning units in buildings and plants
Pharmaceuticals	used in the manufacture of drugs such as sulfonamide which inhibit the growth and multiplication of bacteria that require p-aminobenzoic acid (PABA) for the biosynthesis of folic acids, anti-malarials and vitamins such as the B vitamins nicotinamide (niacinamide) and thiamine.
Pulp and Paper	ammonium hydrogen sulfite, NH4HSO3, enables some hardwoods to be used
Mining and Metallurgy	used in nitriding (bright annealing) steel, used in zinc and nickel extraction
Cleaning	ammonia in solution is used as a cleaning agent such as in ‘cloudy ammonia’
