Vedclass · Answer

(C) During the electrolysis of $CuSO_{4(aq)}$ using graphite electrodes,the following reactions occur:At the cathode: $Cu^{2+}_{(aq)} + 2e^- \rightarrow Cu_{(s)}$At the anode: $2H_2O_{(l)} \rightarrow O_{2(g)} + 4H^+_{(aq)} + 4e^-$As the reaction proceeds,$H^+$ ions are produced at the anode,which increases the concentration of $H^+$ ions in the solution.Since $pH = -\log[H^+]$,an increase in $[H^+]$ leads to a decrease in $pH$.Therefore,the $pH$ of the solution becomes less than $7.0$.
