WebCr (oh)3+IO3^-1-------->I-+CrO4^2- (in basic medium) by ion electron method. Sir it is written in my book to first balance all the atoms other that o and h by seeing increase and decrease in oxidation number. After that balance o by adding h20 to excess side and adding double of that to other side. But in this case the ans is the other way round . 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
