Question

Select the correct answer from the list in brackets:
The ion which is discharged at the anode during electrolysis of copper sulphate solution using copper electrodes as anode and cathode $[C u^{2 +}, O H^{1 -}, S O_{4}^{2 -}, H^{1 +}]$

Open in App

Solution

Correct answer: $C u^{2 +}$

$S 0_{4}^{2 -} A N D O H^{-}$ ions migrate to the anode but neither are discharged.As copper is an active electode,it loses electrons more easily and self-ionizes to give $C u^{2 +}$ ions.
