Description

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.[1] It has been reported as one of the common atmospheric silver corrosion product.[2]

Application

Silver sulfate may be employed in the following studies:

• Iodination reagent in combination with iodine for the synthesis of iododerivatives.[3]
• Synthesis of iodinated uredines.[4]
• Preparation of silver sulfate reagent, which is required for the determination of Chemical Oxygen Demand (COD).[5]
