Persulfate - Wikipedia
Persulfate - Wikipedia

A ,persulfate, (sometimes known as peroxysulfate or peroxodisulfate) is a compound containing the anions SO 2− 5 or S 2 O 2− 8. The anion SO 2− 5 contains one peroxide group per sulfur center, whereas in S 2 O 2− 8, the peroxide group bridges the sulfur atoms.In both cases, sulfur adopts the normal tetrahedral geometry typical for the S(VI) oxidation state.
