उत्तर

The drying agent is quicklime [CaO]. Drying agents such as P2O5 and CaCl2 are not used because they react with ammonia, which is basic.

\[\ce{6NH3 + P2O5 + 3H2O -> \underset{[Ammonium metaphosphate]}{2(NH4)3PO4}}\]

Anhydrous calcium chloride reacts with ammonia to form a solid complex compound.

\[\ce{CaCl2 +4NH3 -> \underset{[a complex compound]}{CaCl2*4NH3}}\]
