Answer:

so what is question

I didn't understand what is this

Answer 2

Answer:

here it is

Explanation:

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 is discharged at the positive carbon (graphite) anode.
