In the electrolysis of brine (concentrate sodium chloride)
the electrolytic cell industrially used is the kellner- solvay cell which the anode consist of a series of graphite ( carbon)
During the electrolysis.
Cathode.Na+ H+
Anode Cl- OH-
The solution is concentrated but we know that sodium is higher in the electrochemical series so therefore can not be displace at the cathode instead Hydrogen ions which is least. on the other hand chlorine ions is close to hydroxide ion (i.e two ions separated them which are BROMINE ions and IODINE ions which are still close. NOTE: when in between the ions are two they are close base on concentration but when more than two they are not close so the one least in the series is discharge) base on concentration chlorine will be displaced.
so the answer is A because at the cathode sodium ions can not be displace instead Hydrogen ions
