Weboxidizing agent is Mn and the element that gets reduced is O. The half-cell oxidation reaction is Mn2+ + 2H 2O = MnO2 +4H + + 2e and the half-cell reduction reaction is 1/4 O 2 + H + + e = ½ H 2O. If equilibrium is achieved in seawater (pH 8) the E0 cell for this reaction would be +0.81 V. Compute the equilibrium constant for the reaction. E0 WebManganese dioxide reacts with potassium hydroxide in the presence of oxygen forms potassium permanganate. 4MnO2 + 4KOH + 3O2 → 4KMnO4 + 2H2O Manganese dioxide reacts with aluminium forming aluminium oxide and water.
