Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Reduction potential
Concept:

An oxidizing agent causes another substance to be oxidized while it itself is reduced.

Solution:

  • The strength of an oxidizing agent is directly proportional to its tendency to gain electrons.


  • The thermodynamic measure of the tendency to gain electrons is the Standard Reduction Potential (\( E^\circ_{red} \)).


  • Therefore, the stronger the oxidizing power of a chemical species, the more positive and higher its standard reduction potential.


Why other options are incorrect:

A strong oxidation potential indicates a strong reducing agent, not an oxidizing agent. EMF refers to the total voltage of a complete cell, not a single species. Redox potential is a generic term.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
