Question

Electrolytic reduction is done to obtain aluminium why

Answer 1

Answer:

Aluminum reacts with and and has a greater affinity for oxygen than does carbon. As a result, exposing aluminum to carbon dioxide, or carbon monoxide at high temperature results in the carbon having the aluminum take the oxygen away from it leaving the poor carbon sitting on the aluminum oxide. So the result is the exact opposite opposite of what you propose!

We produce our aluminum today in electrolytic cells that release the aluminum which settles to the bottom of the cell as a liquid, and the oxygen reacts with the carbon anode and forms a jet of carbon dioxide.

Answer 2

Answer:

As aluminium has great affinity for oxygen, so aluminium oxide is a stable compound. It is not easily reduced by common reducing agents like carbon, carbon monoxide or hydrogen. Hence, electrolytic reduction is chosen as the method for reducing alumina.
