At the anode, 1. Negatively charged Cl- ions are attracted to the anode. 2. Cl- ions lose electrons and are said to be discharged. 3. Pale green chlorine gas is released at the anode. 4. Ionic half equation: 2 Cl-(l) --> Cl2(g) + 2 e-
At the cathode, Positively charged Na+ ions are attracted to the cathode. Na+ ions gain electrons and are said to be discharged. Silvery sodium is deposited at the cathode. Ionic half equation: Na+(l) + e- --> Na(s)
