Write the balanced chemical equation to prepare ammonia gas in the laboratory by using an alkali.

Ammonia gas is obtained by treating ammonium chloride with calcium hydroxide. The balanced chemical equation is: Ca OH 2 Slaked lime + 2 NH 4 Cl Ammonium chloride → CaCl 2 + 2 H 2 O + 3 NH 3 ↑ Ammonia

State why for the preparation of nitric acid, the complete apparatus is made up of glass.

The apparatus used for the laboratory preparation of nitric acid are made of glass completely because the vapours of nitric acid are highly corrosive. They attack rubber, cork and plastics etc.

What is the type of salt formed when the reactants are heated at a suitable temperature for the preparation of nitric acid?

In the preparation of nitric acid, sodium sulphate salt is formed when the sodium nitrate and concentrated sulphuric acid are heated below 200 ° C . NaNO 3 + H 2 SO 4 Conc . → < 200 ° C NaHSO 4 Sodium bisulphate + HNO 3

Name the gas that is produced in the following case. Sulphur is oxidized by concentrated nitric acid.

When the nitric acid reacts with sulphur, nitric acid oxidizes sulphur to sulphuric acid and water is formed with the release of the nitrogen dioxide gas. S + 6 HNO 3 → H 2 SO 4 + 2 H 2 O + 6 NO 2
