Question

when nah is electrolyzed why h is liberated on anode not on cathode?​

Answer 1

Answer:

When an aqueous solution of sodium fluoride is electrolysed, the gas liberated at anode is O 2 and the gas liberated at cathode is H 2 .At cathode, 2H + +2e − →H 2 ↑At anode, 4OH − →2H 2 O+O 2 +4e − The discharge potential of hydrogen ions is lower than the discharge potential of sodium ions.The discharge potential of hydroxide ions is lower than the discharge potential of fluoride ions.
