∙ 11y agoMy thought is that ,that when the electric current is passed through the electrolyte the aluminium from the anode gets attracted towards the cathode as it has positive charge & rest of the impurities get dissolved in electrolyte or get collected in the beaker.therefore,this way the anode decreases.

Then use electrolysis to transfer all the copper from the impure anode to the cathode.
During the electrolysis of Copper sulphate ,at the cathode ,copper and hydrogen both being positively charged migrate towards the cathode.While at the anode
oxidation
Chlorine is produced at the anode. Brine at the cathodeOxidation reaction: 2 Cl- --'anode'--> Cl2 + 2e-
Aluminium metal is formed at the carbon anode (negative).
Chlorine Gas is evolved at the anode.
Cathode - Hydrogen Anode - Oxygen
during the electrolysis of Sodium Chloride chhlorine gas is produced at the anode and hydrogen gas is produced at the cathose.
Hydrogen gas would evolve from the cathode and oxygen gas would evolve from the anode.
For example titanium (electrolysis in water solution).
Aluminium is obtained by electrolysys.
Then use electrolysis to transfer all the copper from the impure anode to the cathode.
the cathode and anode keeps interchanging between each other
If a solution of NaI is electrolyzed, iodine is formed at the anode and hydrogen gas at the cathode. In the instance if it is the molten liquid of NaI, it would emit sodium from the sodium at the cathode and iodine at the anode.
