Potassium persulfate is the inorganic compound with the formula K2S2O8. Also known as potassium peroxydisulfate, it 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.
Potassium persulfate can be prepared by electrolyzing a cold solution of potassium bisulfate in sulfuric acid or by adding potassium bisulfate to ammonium peroxydisulfate solution.
In industry, this substance is produced through the chemical oxidation of potassium sulfate using fluorine.
