Balance the following redox reaction by using oxidation number method. MnO_(2)+Br^(-)toMn^(+2)+Br_(2)+H_(2)O (acid medium)

Balance the following redox reaction by using oxidation number method.

1.	Balance the following redox reaction by using oxidation number method. MnO_(2)+Br^(-)toMn^(+2)+Br_(2)+H_(2)O (acid medium)
Answer» Solution : OXIDATION `underset(-1)(2Br^(-1))overset(2xx1"unit")(to)underset("ZERO")(Br_(2))]xxcancel(2)^(1)` Reduction `MnO_(2) overset(1xx2"unit")(to)underset(+2)MN^(+2)]xxcancel(2)^(1)` ______________________________________ `MnO_(2)+2Br^(-1)toMn^(+2)+2B_(2)` Balancing Hydrogen and Oxygen by adding `H_(2)O` molecules and `H^(+)` ions `MnO_(2)+2Br^(-1)+4H^(+)toMn^(+2)+Br_(2)+2H_(2)O`
