It contains the pyrosulfate anion S2O72− which has a dichromate like structure and can be visualised as two corner sharing SO4 tetrahedra, with a bridging oxygen atom. A semi-structural formula for pyrosulfate ion is O3SOSO32−. In this compound sulfur has an oxidation state of +6. Potassium pyrosulfate is used in analytical chemistry; samples are fused with potassium pyrosulfate, (or a mixture of potassium pyrosulfate and potassium fluoride, KF) to ensure complete dissolution prior to a quantitative analysis. It is also used as a catalyst in conjunction with vanadium(V) oxide, for example.〔''Sulfur trioxide production'' BurkhardtD.B.
