Which of the following statements is correct regarding electrolysis of molten NaCl?
Options
- APale green Cl ₂ gas released at anode
- BMolten silvery white sodium is deposited at cathode
- CDecomposition of NaCl into Na metal and Cl ₂ gas
- DBoth options A and B
Correct answer
D. Both options A and B
Step-by-step solution
During the electrolysis of molten NaCl , the ions present are Na ^+ and Cl ^- . At the cathode (reduction): Na ^+ + e^- Na (l) Since the operating temperature is much higher than the melting point of sodium, molten silvery-white sodium metal is deposited at the cathode. At the anode (oxidation): 2 Cl ^- Cl ₂(g) + 2e^- Pale green chlorine gas is liberated at the anode. Since both statements A and B correctly describe the observations at the respective electrodes during the electrolysis process, the correct choice is
