Stronger the oxidizing agent, greater is the:
Correct answer: D. Reduction Potential
- A. Redox Potential
- B. Oxidation Potential
- C. EMF of the cell
- D. Reduction Potential
Explanation
A stronger oxidizing agent means it undergoes reduction more easily and thus has greater standard reduction potential. Reduction potential (Eo) is defined as a tendency of a chemical species to be reduced by gaining an electron and is defined with electrochemical reference of hydrogen, which is globally given the reduction potential of zero.

About Oxidation and Reduction
Oxidation involves loss of electrons, increase in oxidation number or addition of oxygen, while reduction involves electron gain, decrease in oxidation number or removal of oxygen. The topic covers oxidising and reducing agents, oxidation-number changes, redox equations and the distinction between oxidation at the anode and reduction at the cathode.
