Vedclass · Answer

(A) The electrolysis of pure alumina is not feasible because it is a bad conductor of electricity and its fusion temperature is high. Cryolite $(Na_3AlF_6)$ and fluorspar $(CaF_2)$ are added to alumina $(Al_2O_3)$,which lowers the fusion temperature to approximately $1140 \ K$ and makes the mixture a good electrical conductor. Then,the electrolysis of this fused mixture is carried out.
