WebRedox reactions refer to a pair of reactions in which a particular oxidation is coupled to a corresponding reduction. Although neither can occur independently of the other, it can be helpful to write each oxidation or reduction as a half reaction to help us understand and calculate the flow of energy. WebSo in short, any reaction in which both reduction and oxidation happens at the same time, that will be called as redox reaction. And that's how it gets its name of redox. So both reduction and oxidation should be happening.
