Question

(5) Write the chemical reaction of Electrolysis of alumina
​

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.

Answer 2

$\LARGE{\mathfrak\purple{\underline{\underline{Answer:-}}}}$

Ionization of Alumina:-

2Al2O3 → 6O-2 + 4Al+3

Reaction at  Cathode:-

 4Al+3 + 12e- → 4Al

Reaction at Anode:-

 6O-2 → 3O2 + 12e-, C + O2 → CO2
