The term persulfate (sometimes known as peroxysulfate) refers to ions or compounds containing the anions SO2−
5 or S
2O2−
8.[1] The anion SO2−
5 contains one peroxide group per sulfur center, whereas in S
2O2−
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.[2][3]
Ions
- Peroxomonosulfate ion, SO2−
5 - Peroxydisulfate S
2O2−
8
Acids
- Peroxymonosulfuric acid (Caro's acid), H2SO5
- Peroxydisulfuric acid, H2S2O8
Example salts
- Sodium peroxomonosulfate, Na2SO5
- Potassium peroxymonosulfate, KHSO5
- Sodium persulfate (sodium peroxydisulfate), Na2S2O8
- Ammonium persulfate (ammonium peroxydisulfate), (NH4)2S2O8
- Potassium persulfate (potassium peroxydisulfate), K2S2O8
