How to do a half reaction
WebApr 11, 2024 · Now certainly a manganese salt, say M nO2 could be reduced down to M n2+: M nO2(s) + 4H + + 2e− → M n2+ +2H 2O(l) (ii) And so manganese (IV) dioxide, even though it is as soluble as a brick, has acted as an oxidizing agent that is formally reduced in the redox reaction to give colourless (and soluble) M n( + I I) salt.
