Silver sulfite
# Silver sulfite

Silver sulfite is the chemical compound with the formula $Ag_2SO_3.$ This unstable silver compound when heated and/or in light it decomposes to silver dithionate and silver sulfate.

## Preparation

Silver sulfite can be prepared by dissolving silver nitrate with the stoichiometric quantity of sodium sulfite solution, yielding a precipitation of silver sulfite by the following reaction:

    2 $AgNO_3$ + $Na_2SO_3$ ⇌ $Ag_2SO_3$ + 2 $NaNO_3$

After precipitation then filtering silver sulfite, washing it using well-boiled water, and drying it in vacuum.
