Which is produced at the cathode during the electrolysis of brine in Nelson's cell?
Correct answer: A. H2
- A. H2
- B. Na
- C. Cl2
- D. O2
Explanation
Hydrogen gas is produced at the cathode during the electrolysis of brine (sodium chloride solution) in Nelson's cell. This process involves the reduction of water molecules, leading to the formation of hydrogen gas and hydroxide ions.
