Preparation of ammonia 1, Formed by decay of nitrogenous organic matter NH2coNH2+2H20---> 2NH3+2H20+C02 2. Small scale production 2NH4CL+Ca(oh)2---> 2NH3+2H20 +Cacl2 3. Large scale production Haber process N2+3H2--> 2 NH3 Conditions a. High pressure b. 700k temperature c .Iron oxide used as a catalyst Properties of ammonia Colourless gas with pungent smell, Ammonia molecule is trigonal pyramidal, that is Lewis base Highly soluble in water: NH3+H20---> NH4+ +0H- It forms ammonium salt with acids and it helps the precipitation of many metal hydroxides from their salt solutions Uses: Fertilizers, Liquid ammonia is also used as a refrigerant
