Answer

The ammonia gas is passed through a drying tower before collection of the gas. The drying agent used is quicklime [CaO]
Reason — Quicklime being basic in nature does not react with basic ammonia gas. The drying agents not used are conc. H₂SO₄, P₂O₅ and fused CaCl₂ since they react chemically with ammonia.

Dry ammonia gas is collected by the downward displacement of air as it is lighter than air. Ammonia gas is not collected over water since it is highly soluble in water.
