  • Silver sulfate is mostly used in the silver plating of objects and in electrolysis.
  • For medicinal purposes, it is used as an antimicrobial agent. Silver compounds, especially silver sulfate, are used to saturate bandages used to cover a variety of skin wounds, from minor cuts to severe lacerations and abrasions.
  • The combination of silver sulfate and iodine is an effective reagent for iodinating alkyl, alkoxybenzenes, aromatic amines, and uridines.
  • It serves as a non-staining alternative to silver nitrate.
  • It is also utilized in the production of batteries.


Q. Is Silver Sulfate soluble in water?

Silver sulfate has low solubility in water, i.e. approximately about 0.83 g/100 mL at 25 °C.

Q. What is the chemical formula for Silver Sulfate?

The chemical formula for silver sulfate is Ag2SO4.

Q. Is Silver Sulfate a precipitate?

When an aqueous solution of silver nitrate is reacted with sulfuric acid, silver sulfate separates out as a solid precipitate.
