Electrode potential of Zn
Correct answer: D. depends on the nature of the coupled electrode
- A. Oxidation
- B. Reduction
- C. Oxidation-reduction
- D. depends on the nature of the coupled electrode
Explanation
The electrode potential of Zn itself doesn't have a fixed value like "oxidation" or "reduction." It depends on the specific half-cell reaction involving Zn and the nature of the electrode it's paired with. If Zn undergoes oxidation (loses electrons), the potential will be positive. If it undergoes reduction (gains electrons), the potential will be negative. Therefore, it depends on the specific context of the electrochemical cell.

The more specific you are, the faster it gets fixed. A source beats an opinion.

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.
