Additional information

The inorganic sodium nitrite dissociates immediately into sodium and nitrite ions in water. The nitrite ion is a component of the nitrogen cycle. In the environment, bacteria of the genus Nitrobacter oxidise nitrites to nitrates. Nitrates are reduced to nitrogen by anaerobic bacteria present in soil, sediment and sludge of sewage treatment plants.
