Question
Give reason for the following:
The blue colour of aqueous copper sulphate fades when it is electrolysed using platinum electrodes.

Solution
The blue colour of copper ions fades due to the decrease in Cu+2 ions, and finally, the solution becomes colourless as soon as the Cu+2 ions are finished.
