Redox reactions are those chemical reactions in which both oxidation as well as reduction occur simultaneously.
- Oxidation and reductions go hand in hand.
- The substance which undergo reduction is called oxidising agent while the substance which undergo oxidation is called reducing agent. One can say that the substance that causes the oxidation of any substance in reaction is called the oxidizing agent while the substance that causes the reduction is called the reducing agent.
- Neither reduction nor oxidation occurs alone. Both of them occur simultaneously. Since both these reactions must occur at the same time they are often termed as "redox reactions". The oxidation or reduction portion of a redox reaction, including the electrons gained or lost can be determined by means of a Half-Reaction.
