Question

Why sodium in discharged during electrokysis of conc nacl?

Answer 1

see NaCl is an ionic bond which forms due to transfer of electrons and create electrostatic force whereas when electrolysis done there is more potential difference created in bw electrodes so that sodium attracts to cathode and chlorine to anode

Answer 2

Solution :-


☆ If you look up the electrode potentials, you will see that it's easier to discharge hydroxide ions than chloride ions, so in dilute solution the production of oxygen is preferred. However when the solution is concentrated, the anode is surrounded by lots of chlorides and extremely few hydroxides so it's almost as if the hydroxides are not there and the chlorides are discharged.
