Question

explain electrolysis of copper sulphate solution using platinum anode and copper or platinum cathode​

Answer 1

When Copper(II) sulfate is electrolysed with a copper anode electrode (the cathode can be carbon or copper), the copper deposit on the cathode (–) equals the copper dissolves at the anode (+). Therefore the blue colour of the Cu2+ ions stays constant because Cu deposited = Cu dissolved.

Hope it helps uh.
