Vedclass · Answer

(D) Aluminum is a highly reactive metal,and its oxide,alumina $(Al_2O_3)$,is very stable. It cannot be reduced by common reducing agents like carbon or carbon monoxide because the affinity of aluminum for oxygen is much higher than that of carbon. Therefore,aluminum is extracted from alumina by the process of electrolytic reduction (electrolysis of molten alumina dissolved in cryolite).

By which method is aluminum metal obtained by the reduction of alumina?
