(A) Ammonia is prepared by heating a mixture of calcium hydroxide and ammonium chloride.$Ca(OH)_{2(s)} + 2NH_4Cl_{(s)} \rightarrow CaCl_{2(s)} + 2H_2O_{(l)} + 2NH_{3(g)}$Concentrated sulphuric acid $(H_2SO_4)$ and anhydrous calcium chloride $(CaCl_2)$ are not used to dry ammonia because they react with it.Ammonia is a basic gas,so it reacts with acidic drying agents like $H_2SO_4$ and forms an adduct with $CaCl_2$ $(CaCl_2 \cdot 8NH_3)$.The gas is passed through fresh quicklime ($CaO$,solid calcium oxide lumps) to effectively dry it.Ammonia is collected by upward delivery as it is lighter than air.
