Why Aluminium metal cannot be produced by the electrolysis of aqueous solution of aluminium salt ?

Posted byankushmasterPosted inchemistry

The discharge potential of Al3+  ion is higher than that of H+ , thus if we are using the aqueous solution of aluminium salt the hydronium ions are preferably discharged giving H2 gas at cathode and Al will remain in the solution. Thus we can not get Aluminium metal by electrolysis.
