(B) The electrolysis of aqueous $CuSO_4$ with inert electrodes involves the following reactions: \ At cathode: $Cu^{2+} (aq) + 2e^- ightarrow Cu (s)$ \ At anode: $2H_2O (l) ightarrow O_2 (g) + 4H^+ (aq) + 4e^-$ \ As the reaction proceeds,$H^+$ ions are produced in the solution,which leads to the formation of $H_2SO_4$. \ The increase in the concentration of $H^+$ ions causes the $pH$ of the solution to decrease.
