The hydroperoxide ion, HO2– (aq), reacts with permanganate ion, MnO4– (aq) to produce MnO2 (s) and oxygen gas. Balance the equation for the oxidation of hydroperoxide ion to O2(g) by permanganate ion in a basic solution.
You should make a separate post for another question. Piggy backed onto a previous post is likely to get it overlooked.
MnO4^- + 3e + 2H2O ==> MnO2 + 4OH^-
HO2^- + OH- ==> O2 + 2e + H2O
The two balanced half equations are written above. Multiply equation 1 by 2 and equation 2 by 3, then add the two.
MnO4^- + 3e + 2H2O ==> MnO2 + 4OH^-
HO2^- + OH- ==> O2 + 2e + H2O
