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:
“Constant revolutionizing of production ... distinguish the bourgeois epoch from all earlier ones. All fixed, fast-frozen relations, with their train of ancient and venerable prejudices are swept away, all new-formed ones become antiquated before they can ossify. All that is solid melts into air, all that is holy is profaned, and man is at last compelled to face with sober senses, his real conditions of life, and his relations with his kind.”
—Karl Marx (1818–1883)
“The society based on production is only productive, not creative.”
—Albert Camus (1913–1960)
“Just as modern mass production requires the standardization of commodities, so the social process requires standardization of man, and this standardization is called equality.”
—Erich Fromm (1900–1980)
