What will happen during the electrolysis of aqueous solution of ${\mathrm{CuSO}}_4$ by using platinum electrodes

In electrolysis of aqueous solution of ${\mathrm{CuSO}}_4$ by using Pt electrodes, pure copper will deposit at cathode

At cathode : ${\mathrm{Cu}}^{2+}+2{\mathrm{e}}^{-}\to \mathrm{Cu}$ (Reduction)
