Chemical compound

Silver nitrite is an inorganic compound with the formula AgNO2.

Applications

Silver nitrite has many applications. Notable examples include:


Production

Silver nitrite is produced from the reaction between silver nitrate and an alkali nitrite, such as sodium nitrite. Silver nitrite is much less soluble in water than silver nitrate, and a solution of silver nitrate will readily precipitate silver nitrite upon addition of sodium nitrite:

AgNO3 (aq) + NaNO2 (s) → NaNO3 (aq) + AgNO2 (precipitate)

Alternatively, it can be produced by the reaction between silver sulfate and barium nitrite.
