Which substance is obtained in the solution on electrolysis of aqueous

\mathrm{CuS}{\mathrm{O}_4}

solution using graphite electrodes?

View answer and explanation

Correct option: A

{\mathrm{H}_2}\mathrm{O}

Option B (

H_2SO_4

) is correct because during the electrolysis of aqueous CuSO4 using graphite electrodes, water is oxidized at the anode to produce oxygen gas and sulfuric acid remains in the solution.
