Contents

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.
