1a) Calculate the oxidation number for one atom of Mn in the
KMnO4 using the reaction: 5Fe2+ +
MnO-4 + 8H+
5Fe3+ +Mn2+ + H2O
1b) Considering the change in oxidation number of Mn in the product, how many electrons are gained or lost by Mn in KMnO4 when the reaction is balanced?
Oxidation number of Mn in KMnO4;
1 + x + 2*(-4) = 0
x = +7
OR
Reactant side charge = product side charge
5*(2) + x + 4*(-2) + 8 = 17
10 + x - 8 + 8 = 17
x = +7
In product side, Mn2+
Oxidation number of Mn is +2
Gain of e- = 7 - 2 = 5 ...Answer

In addition to mass balance, oxidation-reduction reactions must be balanced such that the number of electrons lost in the oxidation equals the number of electrons gained in the reduction. This balancing can be done by two methods: the half-reaction method or the oxidation number method. The half-reaction method balances the electrons lost in the oxidation half-reaction with the electrons gained in the reduction half-reaction. In either method H2O(l), OH?(aq), and H+(aq) may be added to complete the mass balance. Which...
