CuSO 4 changes to Cu at the cathode and blue colour of the solution gradually fades (colourless).

Q. Assertion (A) At the end of electrolysis using platinum electrodes, an aqueous solution of $C u S O_{4}$ turns colourless.
Reason (R) During the electrolysis $C u S O_{4}$ changes to $C u (O H)_{2}$ during electrolysis.
