  • Anodes needs to be replaced during the electrolysis of the Alumina because they gets oxidized.
  • During the Electrolysis of the Alumina, Oxygen is deposited at the anode.
  • Now, Anode is made up of the graphite (or Carbon), thus carbon reacts with the Oxygen and forms its oxide.
  • As a result of this Oxidation, we needs to replace the anode from time to time.
