Question: State the relationship between oxidation and oxidising agent in a redox reaction. Give an example of redox reaction showing the relationship between oxidation and oxidising agent. [CBSE, Term 1, Set 1, 2016]
Answer: Oxidation is addition of oxygen or removal of hydrogen. The oxidising agent causes oxidation of other compound by getting reduced itself. e.g.: CuO + H₂ → Cu + H₂O
CuO is getting reduced to Cu so it is an oxidising agent. It oxidises H₂ to H₂O.
