Question

Value of standard electrode potential for the oxidation of \[\ce{Cl-}\] ions is more positive than that of water, even then in the electrolysis of aqueous sodium chloride, why is \[\ce{Cl-}\] oxidised at anode instead of water?

Short Note

Solution

In the electrolysis process of sodium chloride, oxidation of water at anode requires more potential. So \[\ce{Cl-}\] is oxidized anode instead of water.
