Ionisation of NaCl: NaCl -> Na+ + Cl- At Anode : Anions(negatively charged ions) move towards the anode .Therefore, Cl- will move towards anode and get reduced and will loose one electron to form a greenis yellow gas (chlorine) which will evolve at anode. Cl- - e- -> Cl At Cathode : Cations (positively charged ions) move towards the cathode.Therefore, Na+ will move towards cathode and get oxidised and will gain one electron to form sodium element. Na+ + e- -> Na
