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:

  1. Ammonia oxidation: Ammonia (NH3) is oxidized to nitric oxide (NO) in the presence of a platinum-rhodium catalyst.
  2. Nitrogen dioxide formation: Nitric oxide is then oxidized to nitrogen dioxide (NO2) in the presence of oxygen.
  3. 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.

Chemistry Cyanide

Cyanide

Cyanide is a highly toxic chemical compound involving .

Sources of Cyanide

Cyanide can be found naturally in some plants, such as cassava and almonds, and is also produced industrially for various purposes, including:

  • Electroplating
  • Mining
  • Photography
  • Fumigation
  • Metalworking
Toxicity of Cyanide

Cyanide exerts its toxic effects by binding to an enzyme called cytochrome c oxidase, which is essential for cellular respiration. This binding prevents the cells from utilizing oxygen, leading to rapid asphyxiation and cellular death.
