|
Answer» Solution :During electrolysis of alumina, aluminium is deposided at the cathode, MOLTEN aluminium being heavier than the electrolyte, is callected at the bottom of the tank. OXYGEN gas is liberated at the anode. Anode reaction: ` 2O^(--)rarr O_2+4e^(-)` (Oxidation) Cathode raction : `AL^3+3e^(-)rarr Al_(l)` (Reduciton) |
