Why electrolytic reduction is preferred for aluminium?

Open in App

Solution

Aluminium oxide $({Al}_{2} O_{3})$ is a stable compound because Aluminium $(Al)$ has a strong attraction for Oxygen $(O) .$
It is resistant to common reducing agents such as Carbon $(C)$ , Carbon monoxide $(CO)$ , and Hydrogen $(H)$ .
As a result, electrolytic reduction is the method of choice for reducing Alumina.
