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.

Famous quotes containing the word production:
“An art whose limits depend on a moving image, mass audience, and industrial production is bound to differ from an art whose limits depend on language, a limited audience, and individual creation. In short, the filmed novel, in spite of certain resemblances, will inevitably become a different artistic entity from the novel on which it is based.”
—George Bluestone, U.S. educator, critic. “The Limits of the Novel and the Limits of the Film,” Novels Into Film, Johns Hopkins Press (1957)
“The society based on production is only productive, not creative.”
—Albert Camus (1913–1960)
“In the production of the necessaries of life Nature is ready enough to assist man.”
—Henry David Thoreau (1817–1862)
