Silver nitrite is an inorganic compound with the formula AgNO2.
Silver nitrite will react with haloalkanes to give nitro compounds.
Silver nitrite is a white-yellow solid, slightly soluble in water.
Silver nitrite can be bought from lab suppliers and online.
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 + NaNO2 → NaNO3 + AgNO2
- Ag2SO4 + Ba(NO2)2 → 2 AgNO2 + BaSO4
- Preparation of aniline compounds
- Preparation of nitro compounds
Silver nitrite can stain the skin as well as most objects and is toxic if swallowed. Protection gloves should be worn when handling the compound.
In closed amber or opaque plastic bottles, away from sunlight and reducing agents.
Since silver is expensive, it's best to recycle it.
