What is the reaction called when oxidation and reduction take place simultancously ? Explain with one example .

Explanation

i. The reaction in which oxidation and reduction takes place simultaneously is called a redox reaction .
ii. Example : `CuO + H_(2)rarrH_(2)O`
In this reaction , CuO loses oxygen to from Cu . This means that reduction of CuO takes place . `H_(2) ` molecule takes up oxygen to from `H_(2)O.` This means that oxidation of j`H_(2)` takes place. Both the oxidation and reduction reactions alwayes occur simultaneously.
