← ScienceWhich consequence results when molten sodium chloride reaches platinum electrodes?
A)Chlorine gas evolution arises at anode✓
B)Sodium metal deposits on the anode
C)Electrode passivation halts electric passage
D)Platinum chloride deposition causes electrode flaking
💡 Explanation
Chlorine gas forms; molten NaCl undergoes electrolysis due to applied voltage causing *ionic conduction*. Therefore, chloride ions oxidize at the anode to form chlorine gas, rather than sodium deposition, which occurs at the cathode under normal electrolytic conditions.
