Production
The salt is prepared by treating sodium hydroxide with mixtures of nitrogen dioxide and nitric oxide:
- 2 NaOH + NO2 + NO → 2 NaNO2 + H2O
The conversion is sensitive to the presence of oxygen, which can lead to varying amounts of sodium nitrate.
In former times, sodium nitrite was prepared by reduction of sodium nitrate with various metals.
