Formula and structure: The chemical formula of potassium permanganate is KMnO 4 and its molar mass is 158.034 g/mol. Potassium permanganate (KMnO4) has been widely applied as an oxidant for in situ remediation of contaminated groundwater and soil. It leaves a stain on skin or tissues. KMnO4 forms orthorhombic crystals with constants: a = 910.5 pm, b = 572.0 pm, c = 742.5 pm. In the solid (as in solution), each MnO4 centres are tetrahedral. Action of heat: When heated, potassium permanganate decomposes to form potassium manganate and manganese dioxide. 77, No. The Mn–O distances are 1.62 Å. It can react with many. As the oxidation states of atoms increase the elements become more electronegative. A German-Dutch chemist Johann Rudolf Glauber was the first to discover the production of KMnO4 in the year 1659.
