(A) The electrolysis of an aqueous solution of $CuSO_{4}$ with inert electrodes involves the following reactions:At the cathode: $Cu^{2+}_{(aq)} + 2e^{-} \rightarrow Cu_{(s)}$At the anode: $2H_{2}O_{(l)} \rightarrow O_{2(g)} + 4H^{+}_{(aq)} + 4e^{-}$Since $H^{+}$ ions are produced at the anode,the concentration of $H^{+}$ ions in the solution increases.As $pH = -\log[H^{+}]$,an increase in $[H^{+}]$ leads to a decrease in the $pH$ of the solution.
