salts of nitrous acid, HNO2. Nitrites are colorless, crystalline compounds that are thermally less stable than nitrates. The nature of decomposition depends on the cation. For example, 2Ba(NO2)2 = BaO + Ba(NO3)2 + NO2 + ½N2, whereas 2AgNO2 = AgNO3 + Ag + NO.

Almost all nitrites are highly soluble in water (an exception is AgNO2). Nitrites may have both oxidizing and reducing properties.

Nitrites are obtained by the action of a mixture of NO and NO2 on oxides and hydroxides, by the reduction of nitrates, and by exchange reactions. They are used mainly in the production of azo dyes. (The most important nitrites are described in separate articles—see, for example, SODIUM NITRITE.)
