2Na+  +  2e-    ->  2Na (sodium metal at the (-)cathode).
2Cl-  -  2e-    ->  Cl2 (chlorine gas at the (+)anode).

  • Sodium ions gain electrons (reduction) to form sodium atoms.
  • Chloride ions lose electrons (oxidation) to form chlorine atoms.
  • The chlorine atoms combine to form molecules of chlorine gas.

The overall reaction is

2Na+Cl-(l)      ->   2Na(s)  +  Cl2(g)
