Why sodium hydroxide solution is formed near cathode in chlor -alkali process?I Know it is formed at cathode
But why?
Why it doesn't form near anode???

Dear Student,

At anode:-

2Cl^-→Cl2+2e-

At cathode:-

2H₂O+2e^-→H₂+2OH^-

The non-permeable ion exchange membrane at the center of the cell allows Na+ ions to pass in the chamber containing OH- ions and hence NaOH formed at the cathode.

Regards.
