Sodium is going from oxidation state 0 interior the steel to +a million in NaOH. Ca++ ions could have an interest in the negatively charged electrode (the cathode) the place they settle for electrons to offer Ca steel. The negatively charged chloride ions pass to the useful electrode (the anode) the place they supply up electrons and form elemental chlorine gas, Cl2.
