Question
Electrolysis of molten NaCl produces Na and Cl2 here.
- Na is oxidised
- Cl– is oxidised
- Both are oxidised
- None of these are oxidiced or reduced.
Answer
(b) Cl– is oxidised
Explanation:
In the electrolysis of molten NaCl, the chloride ions (Cl–) are oxidized at the anode to form chlorine gas (Cl2), and the sodium ions (Na+) are reduced at the cathode to form sodium metal (Na).
