Potassium pyrosulfate (potassium disulfate) is a chemical compound, K2S2O7. 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 andpotassium 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.

Application

Mainly used as coagulant of warm water, purify water quality. Papermaking industry used as sizing agent, and cooperate with rosin emulsion used for paper sizing, improve the water resistance of paper strength. Pharmaceutical industry as an antiseptic, astringent and hemostatic. Made dry alum, can be used as a topical hemostatic convergence; Match with a certain concentration of aqueous solution, can be used to prevent rice dermatitis; Made of aluminum hydroxide, can be made into stomach trouble.Mixing together with the green fodder and can be used for animal disease prevention and control. Is Chinese traditional medicine pinellia, south star of pickled formulation, etc. Light industry is used as the yellow medical glass colorant and leather industry used as aluminium tanning agent.
