Silver sulfate

Silver sulfate (Ag2SO4) is an ionic compound of silver used in silver plating and as a non-staining substitute to silver nitrate. This sulfate is stable under ordinary conditions of use and storage, though it darkens upon exposure to air or light. It is minimally soluble in water.

This sulfate is stable under ordinary conditions of use and storage, though it darkens upon exposure to air or light. It is minimally soluble in water. Silver sulfate is prepared by adding sulfuric acid to a solution of silver nitrate: AgNO3(aq) + H2SO4(aq) = AgHSO4(aq) + HNO3(aq) 2 AgHSO4(aq) <=> Ag2SO4(s) + H2SO4(aq) reversible reaction
