Downs Cell is used for the electrolysis of?
Correct answer: C. Fused NaCl
- A. Aqueous NaCl
- B. Aqueous NaNO3
- C. Fused NaCl
- D. Fused NaNO3
Explanation
A Down's cell is used for the electrolysis of molten sodium chloride. The battery must supply over 4 volts to carry out this electrolysis. This reaction is a major source of production of chlorine gas and is the only way to obtain pure sodium metal.

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.
