Reduction refers to a process in which something gains electrons, and its oxidation number is reduced.Actually this is not quite where the word came from. More precisely, oxidation is defined 337 0 obj <> endobj 0000001354 00000 n Redox reactions, or oxidation-reduction reactions, are a family of reaction that are concerned with the transfer of electrons between species.
