Solution
The correct option is B Chlorine Chlorine is the resulting product at anode when electrolysis of a dilute solution of sodium chloride occurs. Hydrogen ions having lower discharge (or higher reduction ) potential than sodium ions are liberated at cathode. Simultaneously, chloride ions having lower discharge (or higher reduction potential) than hydroxide ions will be liberated at the anode.
