WebRedox reactions put the two half-reactions (one reduction, one oxidation) together into a complete equation. The electrons lost in the oxidation half-reaction are then gained in the … WebAnd remember, oxidation is losing electrons. Oil rig, reduction is gaining electrons, or reduction is a reduction in the oxidation number. So first, let's look at the iodine. We go from an oxidation number of negative one to zero. So to go from an oxidation number of negative one to zero, you need to lose electrons.
