← ScienceWhich outcome occurs when applying excessive voltage across molten NaCl?
A)Electrolysis produces sodium and chlorine.✓
B)Ionic conductivity increases dramatically.
C)NaCl decomposes into gaseous radicals.
D)Charge carriers undergo band-gap tunneling.
💡 Explanation
Applying excessive voltage causes electrolysis because of the decomposition caused by electron transfer at the electrodes rather than simple conduction. Therefore, sodium and chlorine gas are liberated, rather than just increased conductivity at high potentials.
