The structure of the peroxodisulfate anion

The peroxydisulfate ion, S₂O₈²⁻, is a oxyanion. It is commonly referred to as the persulfate ion, but this term also refers to the peroxomonosulfate ion, SO₅²⁻. Approximately 500,000 tons of salts containing this anion are produced annually. Important salts include sodium persulfate (Na₂S₂O₈), potassium persulfate (K₂S₂O₈), and ammonium persulfate ((NH₄)₂S₂O₈). These salts are colourless, water soluble solids that are strong oxidants.

Applications

Salts of peroxydisulfate are mainly used to initiate the polymerization of various alkenes, including styrene, acryonitrile, and fluoroalkenes. Polymerization is initiated by the homolysis of the peroxydisulfate:

[O₃SO-OSO₃]^2- $\overrightarrow{\leftarrow }$ 2 [SO₄]^-

In addition to its major commercial applications, peroxydisulfate participates in reactions of interest in the laboratory:

• Elbs persulfate oxidation
• Oxidation of Ag⁺ to Ag²⁺
