Short description: Class of chemical compounds
A persulfate (sometimes known as peroxysulfate or peroxodisulfate)[1] is a compound containing the anions SO2−5 or S2O2−8.[2] The anion SO2−5 contains one peroxide group per sulfur center, whereas in S2O2−8, the peroxide group bridges the sulfur atoms. In both cases, sulfur adopts the normal tetrahedral geometry typical for the S(VI) oxidation state. These salts are strong oxidizers.[3][4]
