Persulfate

A persulfate (sometimes known as peroxysulfate or peroxodisulfate)

anions SO²⁻
₅ or S
₂O²⁻
₈.^[2] 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.^[3]^[4]

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
