Dithionate
From Wikipedia, the free encyclopedia
The dithionate anion, S2O62−, is a sulfur oxoanion derived from dithionic acid, H2S2O6. Its chemical formula is sometimes written in a semistructural format, as [O3SSO3]2−.
The sulfur atoms of the dithionate ion are in the +5 oxidation state.
It is a very stable compound with the properties of a strong mineral acid. It is unaffected by many normal oxidizing and reducing reagents, but can be converted to sulfate and sulfur dioxide when boiled with a strong acid such as concentrated hydrochloric acid.
