Sodium chloride is an ionic compound. When it dissolves in water, 4 ions form which are Na+, Cl-, OH- & H+. The sodium chloride dissociates into its ions and the water ionises to form ions. Hydrogen is less reactive than sodium so forms hydrogen at the cathode. Halide ions discharge more easily than hydroxide ions so forms chlorine gas at the anode. The hydrogen ions are reduced as they gain electrons. The chloride ions are oxidised as they lose electrons.

Thank you. Very use ful
Best explanation till know
Best explanation ever
this helped me so much to understand electrolysis ! thank you !!
Simply superb explanation
It's so useful for me, thx you for making this meaningful video.
What will happen to naoh.. Will oxidation and reduction take place again for naoh?
how did you know the solution was water (H2O)
Why bubbles of gas chlorine forms after some time at anode?? Plz reply
