How are reduction and half reactions used to balance redox reactions?
Notice that in the overallreaction the reduction half-reaction is multiplied by two. This is so that the number of electrons gained in the reduction half-reaction match the number of electrons lost in the oxidation half-reaction. Balancing redox reactions (ESCR2) Half-reactions can be used to balance redox reactions.
