ICSE Class 10 Answered
why can't sodium be discharged at the cathode instead of hydrogen during electrolysis of concentrated NaCl solution?
Asked by saibaba1069 | 25 Jul, 2020, 11:24: PM
Expert Answer
Sodium ions and hydrogen ions (from the water) arrive, but sodium is so high in the electrochemical series that its ions aren't discharged and H+ ions are at lower position in series so it is discharged.
