Application

Silver sulfate may be employed in the following studies:
  • Iodination reagent in combination with iodine for the synthesis of iododerivatives.
  • Synthesis of iodinated uredines.
  • Preparation of silver sulfate reagent, which is required for the determination of Chemical Oxygen Demand (COD).

General description

Silver sulfate (Ag2SO4) is the disilver(I) salt of sulfuric acid. It participates in the TiO2-assisted photooxidation of substituted benzyltrimethylsilanes in acetonitrile. Diarylethanes were obtained in 50-74% yields. It has been reported as one of the common atmospheric silver corrosion product.
