Value of standard electrode potential for the oxidation of `Cl^(-)` ions is more positive than that of water, even then in the electrolysis of aqueous sodium chloride, why is `Cl^(-)` oxidised at anode instead of water?

Value of standard electrode potential for the oxidation of `Cl^(-)` io

1.	Value of standard electrode potential for the oxidation of `Cl^(-)` ions is more positive than that of water, even then in the electrolysis of aqueous sodium chloride, why is `Cl^(-)` oxidised at anode instead of water?
Answer» Oxidation of `H_(2)O` to `O_(2)` is kinetically so slow that it needs some overvoltage. Hence, `Cl^(-)` is oxidized instead of water.
