Give an example of a redox reaction.

The reactions in which both oxidation and reduction takes place simultaneously are known as redox reactions.

An example of a redox reaction is:-

Fe₂O₃ + 3CO → 2Fe + 3CO₂

In the above reaction ferric oxide (Fe₂O₃) is reduced into iron (Fe) by losing the oxygen atoms attached to it and carbon monoxide (CO) is oxidized into carbon dioxide (CO₂) by gaining the oxygen atoms.
