The electrolysis product of molten NaCl at electrodes:
Correct answer: A. Na and Cl2
- A. Na and Cl2
- B. H2 and Cl2
- C. Na and NaOH
- D. H2, Cl2 and NaOH
Explanation
In the electrolysis of molten NaCl, sodium ions (Na+) move to the cathode where they gain electrons to form sodium metal (Na). At the anode, chloride ions (Cl-) lose electrons to form chlorine gas (Cl2). Thus, the products are sodium metal and chlorine gas. Options involving hydrogen and sodium hydroxide are incorrect because these substances are not produced in the electrolysis of molten NaCl.

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.
