The redox reaction below occurs in acidic solution. Balance it with the smallest whole number coefficients and determine the coefficient for H+.
MnO4-(aq) + HNO2(aq) ---> Mn2+(aq) + NO3-(aq)
Mn goes from an oxidation state of +7 on the left to +2 on the right. N goes from an oxidation state of +3 on the left to +5 on the right.
