IUPAC NAME: dipotassium;sulfonatooxy sulfate

Potassium Peroxodisulfate is the inorganic compound with the formula K2S2O8.
Also known as potassium peroxydisulfate or KPS, Potassium Peroxodisulfate is a white solid that is sparingly soluble in cold water, but dissolves better in warm water.
This salt is a powerful oxidant, commonly used to initiate polymerizations.

Preparation of Potassium Peroxodisulfate:
Potassium Peroxodisulfate can be prepared by electrolysis of a cold solution potassium bisulfate in sulfuric acid at a high current density.
2 KHSO4 → K2S2O8 + H2
Potassium Peroxodisulfate can also be prepared by adding potassium bisulfate (KHSO4) to a solution of the more soluble salt ammonium peroxydisulfate (NH4)2S2O8.
In principle Potassium Peroxodisulfate can be prepared by chemical oxidation of potassium sulfate using fluorine. Several million kilograms of the ammonium, sodium, and potassium salts of peroxydisulfate are produced annually.

Uses:
This salt is used to initiate polymerization of various alkenes leading to commercially important polymers such as styrene-butadiene rubber and polytetrafluoroethylene and related materials.
In solution, the dianion dissociates to give radicals:
[O3SO-OSO3]2− ⇌ 2 [SO4]•−
