Moderate

The element which has greatest value of standard reduction potential (E°red) in the redox reaction acts as:

Correct answer: B. Strongest oxidizing agent

  • A. Strongest reducing agent
  • B. Strongest oxidizing agent
  • C. Weakest oxidizing agent
  • D. Weakest reducing agent

Explanation

Lithium having the largest negative value of electrode potential, is the strongest reducing agent. By convention, the standard electrode potentials are reduction potentials, or the tendency to be reduced. By that convention, the strongest reducing agents will have large negative potentials.Lithium, having the largest negative value of electrode potential, is the strongest reducing agent.

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.
