A permanganate is the general name for a chemical compound containing the manganate(VII) ion, (MnO 4 â).Because manganese is in the +7 oxidation state, the permanganate(VII) ion is a strong oxidizing agent. The ion has tetrahedral geometry. H+ + MnO 4 â + 5 e â â Mn 2+ + 4 H 2 O. In a strongly basic solution, permanganate(VII) is reduced to the green +6 oxidation state of the manganate ion, MnO 4 2â .
* MnO2 is used in combination with anthracite, sand, and gravel in industrial water treatment plants. * Manganese dioxide also catalyses the decomposition of hydrogen peroxide to oxygen and water: 2 H2O2(aq) â O2(g) + 2 H2O(l) * Eighteenth-century British chemists referred to MnO2 simply as manganese.Elemental manganese was known as regulus of manganese. * Ancient cave painters used MnO2 as a black or brown pigment. MnO2 was used for production of chlorine in the eighteenth century, before being displaced by electrolytic methods. The manganese dioxide was subsequently recovered by the Weldon process. * Earliest glassmakers used MnO2 to remove the natural bluish-green tint of glass, or to add a pinkish or purplish color.
