Complete and balance the following redox equation. Show all work and both half reactions. H2S + MnO4- ------> Mn2+ + (SO4)2- (acidic solution) Solution 5 H2S + 8 MnO4- + 14 H+ ---> 8 Mn2+ + 5 SO4 2- + 12 H2O Sulfur is oxidized, oxidation state of 2- going to 6+; loses 8 electrons Manganese is reduced, oxidation state of 7+ going to 2+, gains 5 electrons that\'s where we get the coefficients of 5 and 8 then add sufficient H+ ions (it\'s an acidic solution) on the left and H2O molecules on the right to balance (add H2O to balance oxygen, then add H+ to balance hydrogen).
