Question

what is used as dry agent in ammonia

Answer 1

Answer:

Explanation:

The ammonia formed is dried using an unusual drying agent - calcium oxide, cao (quicklime). Ammonia is made commercially by the direct combination of nitrogen and hydrogen using a catalyst - finely reduced (or divided) iron impregnated with aluminium oxide.

Quick lime is basic in nature and hence does not react with ammonia, which is also basic in nature, whereas all other drying agents are acidic in nature .

Answer 2

As ammonia is basic in nature it can only be dried by a basic agent. Otherwise it can react with the during agent. Concentrated sulphuric acid or phosphorus pentoxide cannot be used here. We can use dry calcium hydroxide or Calcium Chloride to dry ammonia.

Hope this helps you.
