← ScienceWhich outcome results when the sodium chloride melt electrolysis is run?
A)Chlorine gas forms at anode✓
B)Sodium ions dissolve in water
C)Hydrogen evolution favors the cathode
D)Sodium chloride precipitates rapidly
💡 Explanation
Chlorine gas will form because oxidation through electron transfer happens at the anode during electrolysis; electrolytic decomposition reaction splits NaCl into sodium and chlorine. Therefore, elemental chlorine byproduct is present, rather than others, during NaCl melt electrolysis.
