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.[3] 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.
