Persulfate
The term persulfate (sometimes known as peroxysulfate) refers to ions or compounds containing the anions [SO5]2- or [S2O8]2-.[1] The anion [SO5]2- contains one peroxide group per sulfur center, whereas in [S2O8]2-, the peroxide group bridges the sulfur atoms. In both cases, sulfur adopts the normal tetrahedral geometry typical for S(VI) oxidation state. These salts are strong oxidizers.[2]
