When elements are arranged in the order of their standard electrode potential on the basis of hydrogen scale, the resulting list of elements is known as electrochemical series. Mark the incorrect statement about electrochemical series:
Correct answer: D. E°red increases from bottom to top
- A. Every top metal can displace lower one in redox reaction
- B. Every lower non-metal can displace higher one in redox reaction
- C. E°cell =E°oxid + E°red
- D. E°red increases from bottom to top
Explanation
Reduction potential increases from top to bottom.

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.
