![]() In a neutral medium, however, it gets reduced to the brown +4 oxidation state of manganese dioxide MnO 2.Ĥ + 3 e − → MnO 2 + 4 OH − Production In a strongly basic solution, permanganate(VII) is reduced to the green +6 oxidation state of the manganate ion, MnO 2− In an acidic solution, permanganate(VII) is reduced to the pale pink +2 oxidation state of the manganese(II) (Mn 2+) ion. For example, trichloroethane (C 2H 3Cl 3) is oxidized by permanganate ions to form carbon dioxide (CO 2), manganese dioxide (MnO 2), hydrogen ions (H +), and chloride ions (Cl −). ![]() The exact chemical reaction is dependent upon the organic contaminants present and the oxidant utilized. Permanganate solutions are purple in color and are stable in neutral or slightly alkaline media. The ion is a transition metal oxo complex with tetrahedral geometry. ![]() Because the manganese atom is in the +7 oxidation state, the permanganate(VII) ion is a strong oxidizing agent. A permanganate ( / p ər ˈ m æ ŋ ɡ ə n eɪ t, p ɜːr-/) is a chemical compound containing the manganate(VII) ion, MnO −Ĥ, the conjugate base of permanganic acid. ![]()
