उत्तर
The substance used for drying ammonia gas is quicklime( calcium
oxide) .Concentrated sulphuric acid, anhydrous calcium chloride and phosphorus pentoxide cannot be used for drying ammonia gas because ammonia being basic reacts wi th them, and the following reaction takes place
Conc.H2SO4 reacts with ammonia to form ammonium sulphate.
2 NH3 + H2SO4(conc..) → (NH4)2SO4
Phosphorus pentoxide reacts with ammonia to form ammonium phosphate.
6 Nh3 + P2O5 + 3H2O → 2(NH4)3PO4
Anhydrous calcium chloride combines with ammonia to form addi tion compound.
4 NH3 + CaCI2 → CaCI2. 4NH3
