Silver sulfate is the inorganic compound with the formula Ag2SO4. It is a white solid with low solubility in water.




Preparation and structure


Silver sulfate precipitates as a solid when an aqueous solution of silver nitrate is treated with sulfuric acid:

2 AgNO3 + H2SO4 → Ag2SO4 + 2 HNO3
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.




Silver(II) sulfate


The synthesis of silver(II) sulfate (AgSO4) with a divalent silver ion instead of a monovalent silver ion was first reported in 2010 by adding sulfuric acid to silver(II) fluoride (HF escapes). It is a black solid that decomposes exothermically at 120 °C with evolution of oxygen and the formation of the pyrosulfate.

AgF2 + H2SO4 → AgSO4 + 2 HF
4 AgSO4 → 2 Ag2S2O7 + O2
