Vedclass · Answer

(B) Aluminium $(Al)$ is extracted by the electrolytic reduction method (Hall-Heroult process). In this process,alumina $(Al_2O_3)$ is dissolved in molten cryolite $(Na_3AlF_6)$ and fluorspar $(CaF_2)$,which lowers the melting point of the mixture and increases electrical conductivity. Electrolysis is carried out in a steel tank lined with carbon (acting as cathode),and graphite rods are used as the anode. During electrolysis,aluminium is deposited at the cathode,while oxygen gas is liberated at the anode.
