Dithionite
The dithionite is the oxoanion with the formula [S2O4]2−. It is commonly encountered as the salt sodium dithionite. For historical reasons, it is sometimes called hydrosulfite, but it contains no hydr
Sulfate
The sulfate or sulphate ion is a polyatomic anion with the empirical formula SO2−4. Salts, acid derivatives, and peroxides of sulfate are widely used in industry. Sulfates occur widely in everyday lif
Dithionate
The dithionate (or metabisulfate) anion, S2O2−6, is a sulfur oxoanion derived from dithionic acid, H2S2O6. Its chemical formula is sometimes written in a semistructural format, as [O3SSO3]2−. It is th
Peroxydisulfate
The peroxydisulfate ion, S2O2−8, is an oxyanion, the anion of peroxydisulfuric acid. It is commonly referred to as persulfate, but this term also refers to the peroxomonosulfate ion, SO2−5. It is also
Tetrathionate
The tetrathionate anion, S4O2−6, is a sulfur oxoanion derived from the compound tetrathionic acid, H2S4O6. Two of the sulfur atoms present in the ion are in oxidation state 0 and two are in oxidation
Fluorosulfates
The fluorosulfates or fluorosulfonates are a set of salts of fluorosulfuric acid with an ion formula SO3F−. The fluorosulfate anion can be treated as though it were a hydrogen sulfate anion with hydro
Disulfite

Persulfate
A persulfate (sometimes known as peroxysulfate or peroxodisulfate) is a compound containing the anions SO2−5 or S2O2−8. The anion SO2−5 contains one peroxide group per sulfur center, whereas in S2O2−8
Sulfite
Sulfites or sulphites are compounds that contain the sulfite ion (or the sulfate(IV) ion, from its correct systematic name), SO2−3. The sulfite ion is the conjugate base of bisulfite. Although its aci
Hyposulfite
Hyposulfite may refer to:
* The thiosulfate anion (S2O2−3)
* Sodium thiosulfate, a salt containing the thiosulfate anion
* S2O2−2, a reported sulfur oxyanion. However salts containing S2O2−2 and HS
Peroxomonosulfate
The peroxomonosulfate ion, SO2−5, is a sulfur oxoanion. It is sometimes referred to as the persulfate ion, but this term also refers to the peroxydisulfate ion, S2O2−8. Its other IUPAC names are sulfu
Thiosulfate
