Q. 21 B5.0( 3 Votes )

Give two examples each of:

Redox reactions

Answer :

The reactions in which oxidation and reduction are taking place at the same time are called redox reactions.

For examples:



In the above example, Fe2O3 is reduced to Fe by losing oxygen atoms.


Thus, Fe undergoes reduction.


CO is oxidized to CO2 by gaining oxygen atom. Thus, C undergoes oxidation.


CuO + H2 Cu + H2O


In the given reaction, CuO is reduced to Cu by losing oxygen. Thus, Cu undergoes reduction.


H2 is oxidized to H2O by gaining oxygen atom. Thus, H2 undergoes oxidation.
