Stronger is the oxidizing agent greater is the___________________?
Correct answer: D. standard reduction potential
- A. Oxidation potential
- B. Redox potential
- C. e.m.f of cell
- D. standard reduction potential
Explanation
An oxidising agent accepts electrons, so its tendency to be reduced is measured by its standard reduction potential. A stronger oxidising agent has a more positive standard reduction potential, E°red. Students may choose oxidation potential by reversing the direction of the half-reaction and therefore using the wrong potential.

About Standard Hydrogen Electrode
The standard hydrogen electrode provides the reference potential of 0.00 V for measuring electrode potentials. It consists of platinum in contact with hydrogen gas at standard pressure and hydrogen ions at standard concentration, usually at 25°C, and can operate as either the oxidation or reduction half-cell.
