Electrolysis of dilute NaCl solution produces Cl2 at anode. This is because of
Overpotential of Na
Overpotential of H2
Overpotential of O2
Overpotential of Cl2
Electrolysis of dilute NaCl solution produces Cl2 at anode due to overpotential of O2
Which of the following statements are correct?
a) The electrolysis of aqueous NaCl produces hydrogen gas at the cathode and chlorine gas at the anode .
b) The electrolysis of a CuSO4 solution using Pt electrodes causes the liberation of O2 at the anode and the deposition of copper at the cathode .
c) Oxygen and hydrogen are produced at the anode and cathode during the electrolysis of dilute aqueous solution of H2SO4 .
