Peroxydisulfuric acid is the inorganic compound with the chemical formula $\mathrm{H}_{2} \mathrm{S}_{2} \mathrm{O}_{8}$.
Peroxydisulfuric acid is the inorganic compound with the chemical formula $\mathrm{H}_{2} \mathrm{S}_{2} \mathrm{O}_{8}$.
It contains sulfur in its +6 oxidation state and a peroxide group.
The tetrathionate anion, $\mathrm{S}_{4} \mathrm{O}_{6}^{2-}$, is a sulphur oxoanion derived from the compound tetrathionic acid, $\mathrm{H}_{2} \mathrm{S}_{4} \mathrm{O}_{6}$.
Two of the sulphur atoms present in the ion are in oxidation state $\mathrm{O}$ and two are in oxidation state $+5 .$
