Answer 1

Answer:

1) cathode is graphite lining of the tank

anode is graphite rods dripped in the tank

2) cryolite and flouspar reduces melting point of alumina to 1000°c due to which it makes the reduction process more easier.

c) cathode reaction

Al³- + 3e- = Al

anode reaction

O4e- =O + 4e-
