Question

Al⁺³ ,Cu⁺² ,Na⁺ ,Zn⁺² ions are present in aqueous solution, such that the concentration of ions is same, write the order of discharge of ions.

Answer 1

The order of discharge of ions is Al⁺³ ,Cu⁺² ,Na⁺ ,Zn⁺² because as the concentration is same, an ion placed lower in electrochemical series get preferentially discharged.
