Silver sulfate is an inorganic compound with the formula Ag2SO4. It is a white solid with low solubility in water.
Preparation and structure
Silver sulfate precipitates when an aqueous solution of silver nitrate is treated with sulfuric acid:
It is purified by recrystallization from concentrated sulfuric acid, a step that expels traces of nitrate. Silver sulfate and anhydrous sodium sulfate adopt the same structure.
