The potential set up when an electrode is in contact with 1M solution of its ions at 298 K is known as standard electrode potential (or standard reduction potential denoted by E°). All of the following statements about standard electrode potential are correct EXCEPT:
Correct answer: D. E°red of Cl2 is maximum (+2.87V)
- A. The smaller the E°red, the greater the reducing power of a metal
- B. E°rcd of Li1 is minimum (-3.04V)
- C. The greater the E°red, the greater the oxidizing power of a non-metal
- D. E°red of Cl2 is maximum (+2.87V)
Explanation
The statement that E°red of Cl2 is maximum (+2.87V) is incorrect. Chlorine has a high E°red because it is a strong oxidizing agent. However, the maximum E°red for any substance is +1.23V, which is the value for fluorine. Therefore, the E°red of Cl2 cannot be greater than +1.23V.

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.
