Template:Short description A persulfate (sometimes known as peroxysulfate or peroxodisulfate)[1] is a compound containing the anions Template:Chem/link or Template:Chem/link.[2] The anion Template:Chem/link contains one peroxide group per sulfur center, whereas in Template:Chem/link, 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]
