alleryElectrolysis of fused sodium chloride produces sodium at the
ACathode by reduction of Na+ ions
BAnode by oxidation of Na+ ions
CCathode by oxidation of Cl- ions
DAnode by reduction of Cl- ions
Answer & Solution
Correct answer: A. Cathode by reduction of Na+ ions
1. At the cathode, positive ions gain electrons (reduction).
2. Na+ + e- -> Na is the cathode reaction.
3. Cl- ions lose electrons at the anode to form Cl2.
4. So metallic sodium forms at the cathode.
