Persulfate - Wikipedia
A persulfate (sometimes known as peroxysulfate or peroxodisulfate) [1] is a compound containing the anions SO 2− 5 or S 2 O 2− 8. [2] 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 ...
Sodium persulfate - Wikipedia
Sodium persulfate is the inorganic compound with the formula Na 2 S 2 O 8. It is the sodium salt of peroxydisulfuric acid, H 2 S 2 O 8, an oxidizing agent. It is a white solid that dissolves in water. It is almost non-hygroscopic and has good shelf-life.
