Question

For drying ammonia gas sulphuric acid is used as dehydrating agent – True or False?

• A. True
• B. False

Answer 1

The correct option is B False

Sulphuric acid reacts with ammonia to form ammonium sulphate
$H_{2}S{O}_4+2N{H}_3\to (N{H}_4{)}_{2}S{O}_4$
Therefore, CaO is used to dry ammonia gas
$CaO+H_{2}O\to Ca(OH{)}_2$
