प्रश्न
Explain, by giving an example, how oxidation and reduction proceed side by side.
उत्तर
It can be explained by the following example:
CuO + H2 → Cu + H2O
In this reaction, CuO gets reduced to Cu by losing oxygen and H2 gets oxidised to H2O by gaining oxygen. Hence, oxidation and reduction proceed side by side.
