Vedclass · Answer

(D) Aluminium metal is extracted by the electrolytic reduction of alumina $(Al_2O_3)$.Since alumina has a very high melting point and is a poor conductor of electricity,it is dissolved in molten cryolite $(Na_3AlF_6)$ and fluorspar $(CaF_2)$.This mixture melts at approximately $900^{\circ} C$ and allows for the electrolysis process.During electrolysis,metallic $Al$ is liberated at the cathode.

The element which could be extracted by electrolytic reduction of its oxide dissolved in a high temperature melt is:
