प्रश्न
Why drying agents such as \[\ce{P2O5}\] and \[\ce{CaCl2}\] are not used to dry \[\ce{NH3}\]?
उत्तर
The drying agent used is \[\ce{CaO}\] in the case of ammonia.
Other drying agents like \[\ce{P2O5}\] and \[\ce{CaCl2}\] are not used. As ammonia is basic, it reacts with them.
\[\ce{6NH3 + P2O5 + 3H2O -> \underset{[Ammonium metaphosphate]}{2(NH4)3PO4}}\]
\[\ce{CaCl2 +4NH3 -> \underset{a complex compound}{CaCl2*4NH3}}\]
