Electrolytic reduction of $Al_2O_3$

Vedclass · Answer

(A) Aluminum is a highly reactive metal,and its oxide $(Al_2O_3)$ is very stable. Carbon reduction is not feasible because the temperature required is extremely high. Therefore,the extraction is carried out by the electrolytic reduction of $Al_2O_3$ dissolved in molten cryolite $(Na_3AlF_6)$ and fluorspar $(CaF_2)$,which lowers the melting point and increases conductivity.

The extraction of aluminum from its oxide $(Al_2O_3)$ is done by:
