Chemistry Nitric Acid

Nitric Acid

Nitric acid is a highly corrosive, toxic, and oxidizing mineral acid involving processes.

Production

Nitric acid is produced industrially by the Ostwald process, which involves the following steps:

Ammonia oxidation: Ammonia (NH₃) is oxidized to nitric oxide (NO) in the presence of a platinum-rhodium catalyst.
Nitrogen dioxide formation: Nitric oxide is then oxidized to nitrogen dioxide (NO₂) in the presence of oxygen.
Absorption: Nitrogen dioxide is absorbed in water to form nitric acid.

Environmental impact

Nitric acid can have a negative impact on the environment. It can contribute to air pollution by releasing nitrogen oxides into the atmosphere. It can also contaminate water sources and soil.
