Start from scratch and separate into half-reactions MnO4-(aq) -----> Mn(^2+)(aq) SO3(^2-)(aq) ----> SO4(^2-)(aq) Balance O by adding H2O as needed: MnO4-(aq) -----> Mn(^2+)(aq) + 4H2O(l) SO3(^2-)(aq) + H2O(l) ----> SO4(^2-)(aq) balance H by adding H+:
2MnO4{-}(aq)+5 SO3{2-}(aq)+6 H{+}(aq)→2 Mn{2+}(aq) + 5 SO4{2-}(aq) + 3 H2O(l) 2 I{-}(aq) + 4 H{+}(aq) + 2 NO2{-}(aq) → 2 NO(g) + 2 H2O(l) + I2(s)
