What will be pH of aqueous solution of electrolyte in electrolytic cell during electrolysis of

\mathrm{CuS}{\mathrm{O}_4}\left( {aq} \right)

between graphite electrodes?

View answer and explanation

Correct option: C

pH < 7.0

Option C (pH < 7.0) is correct because the electrolysis of CuSO4(aq) produces H2SO4, which is acidic.
