Aqueous solution of copper sulphate is subjected to electrolysis using Pt electrodes. False statement about this process is

Upon electrolysis of aqueous CuSO4 solution, At anode: As the discharge potential of water is lower than Sulphate ion, Water undergoes oxidation to liberate oxygen.2H2O→4H++O2+4e;At cathode: Cupric ion gets reduced to copper.Cu+2+2e→Cu×2With the progress of electrolysis, Cu+2ions are replaced by H+1ions. So, there will be gradual increase in H+1ion concentration that decreases the pH.Aqueous copper sulphate is blue in colour; with the loss of Cu+2 ions gradually it changes to colourless due the formation of sulphuric acid solution.
