Molten NaCI conducts electricity due to the presence of
Correct answer: C. Free ions
- A. Free electrons
- B. Free molecule
- C. Free ions
- D. Atoms of Na and Cl
Explanation
When NaCl is melted (in its molten state), the crystal lattice breaks down, separating the sodium (Na+) and chloride (Cl-) ions.These free-moving ions are responsible for conducting electricity as they can carry charge through the molten NaCl.The presence of free ions enables the flow of electric current in the molten state, making it a conductor of electricity.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
