Question

explain the electrolisys reduction of aluminium with diagram​

Answer 1

Answer:

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. ... Aluminium is more dense than the alumina/cryolite solution and so it falls to the bottom of the cell where it can be tapped off as pure liquid metal.

Answer 2

Answer:


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.
