Sodium nitrite

Sodium nitrite is a white or slightly yellow powder, as well as its aqueous solutions. It has the chemical formula NaNO₂. You can also find such names as diazoting salt, erinitrit. The powder dissolves easily. It is oxidized by oxygen in the air to sodium nitrate. In chemical reactions it acts as a strong reducing agent. Available in powder or solution form.

Areas of use

The chemical compound sodium nitrite is poisonous and hazardous to health in high concentrations.

In construction, sodium nitrite is added to concrete mixtures to prevent it from freezing. Thus, this additive allows you to work in winter, with temperatures down to -15 C. Sodium nitrate is also used to slow down the corrosion process in air.

Due to its antioxidant properties, sodium nitrite is used in photography.

Where else is sodium nitrite used:

  • In the production of rubber.
  • In the textile industry.
  • In the production of chemical raw materials based on nitro groups.
  • In metallurgy for surface treatment of metals.
  • In medicine, biology and veterinary medicine.
  • In the pulp and paper industry.
  • In case of poisoning, cyanide acts as an antidote.
  • For the separation of iodine from iodites in technological processes.

This technical substance is packaged in plastic bags, enclosed in paper or other polyethylene bags. All these precautions are related to the toxicity of the reagent.
