← ScienceWhich outcome arises when molten sodium chloride is electrolyzed using inert electrodes?
A)Metallic sodium forms at the cathode✓
B)Chlorine gas dissolves into the electrolyte
C)Sodium hydroxide precipitates at the anode
D)Hydrogen gas evolves from adsorbed moisture
💡 Explanation
When molten sodium chloride undergoes electrolysis, electron transfer at the cathode causes reduction of sodium ions to metallic sodium because sodium is more easily reduced than chloride. Therefore metallic sodium is produced, rather than chlorine dissolution, sodium hydroxide precipitation, or hydrogen evolution, which require different electrochemical reactions or solution conditions.
