Sodium NitriteSodium Nitride, Formula, Chemical Properties, Preparation, Application

Sodium Nitrite

Sodium nitrite is an inorganic compound that has contained the strong reactive agent which is reacted with the bacterias in the food as a food preservative. sodium nitrite is very soluble and hygroscopic in nature. It should be the more effective for the manufacturing the chemicals at the industrial perspective. Moreover these salt has the ability to destroy the poisoning substances in the food raw materials. The systematic IUPAC name is known as sodium nitrite . The chemical or molecular formula of sodium nitrite is NaNO2.

Structural Formula

This is the structural formula of the sodium nitrite:

Sodium Nitrite

 

Chemical Formula

The chemical formula of the sodium nitrite is NaNO2.

Preparation Method

In the aqueous solution, the nitrogen oxides is used to oxidant the nitrogen atoms to produce the sodium nitrite. This is the one of the method for manufacturing the nitrite. In the another method, the nitrate salts has been exposed by the process of heating, ionizing the radiation, lighting and electrolytic reductions. These sodium nitrite is used to destroy the sodium azide in the laboratory.
