explain ::

electrolysis of alumina is done ​

Answer 1

Answer:

Electrolysis of the alumina/cryolite solution gives aluminium at the cathode and oxygen at the anode. Aluminium is more dense than the alumina/cryolite solution, and so falls to the bottom of the cell where it can be tapped off as pure liquid metal. ... Oxygen reacts with the carbon anode to form carbon dioxide gas
