Explanation:

Ostwald process to manufacture nitric acid-

Step 1: Catalytic oxidation of Ammonia

A mixture of dry air and dry ammonia in the ratio of 10:1 by volume is compressed and then passed into a platinum gauze which acts as catalyst at about 800℃.

4NH3+5O2⟶4NO+6H2O+Heat

Step 2: Oxidation of nitric oxide

Nitric oxide combines with oxygen to form nitrogen dioxide at about 50°C.

2NO+O2⟶2NO2

Step 3: Absorption of nitrogen dioxide in water

The nitrogen dioxide and oxygen present in the air react with water to form nitric acid.

4NO2+2H2O+O2⟶Nitric acid4HNO3

Nitric acid obtained is concentrated above 50%. On further distillation, 68% nitric acid is produced.
