Answered by saaidon

Explanation:

Aluminium oxide (Al2O3) is an ionic compound. When it is melted the Al3+ and O2- ions are free to move and conduct electricity. Electrolysis of the alumina/cryolite solution gives aluminium at the cathode and oxygen at the anode. 4Al3+ + 12e- → 4Al (aluminium metal at the (-)cathode) reduction.
