Ammonia gas is usually prepared in the lab by gently heating ammonium chloride and slaked lime . Ammonia gas is lighter than air, necessitating it's collection by the downword displacement of air .Because it is highly soluble in water it cannot be collected over it.

Hey dear,
● Preparation of ammonia -
- In laboratory, ammonia is prepared by gently heating ammonium chloride with calcium hydroxide.
2(NH4Cl) + Ca(OH)2 → (CaCl)2 + 2(NH3) + 2(H2O)
- Ammonia gas formed here is collected by downward displacement of air.
- Finely divided iron or alumina can be used as catalyst in this reaction.
Hope this helps you. Thanks for asking..
