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.
Solution
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.
