Balance Redox Reaction Example Problem - ThoughtCo
Identify what is being oxidized and what is being reduced. To identify which atoms are being Break the reaction into two half-reactions: oxidation and reduction. Oxidation: Cu → Cu. Reduction: Balance each half-reaction by both stoichiometry and electronic charge. This is accomplished by Equalize the electron transfer. In redox reactions, the number of electrons gained must equal the See all full list on thoughtco[PDF]
