Oxidation Potential vs. Reduction Potential: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 18, 2024
Oxidation potential measures the tendency of a substance to lose electrons, while reduction potential measures its tendency to gain electrons.

Key Differences

Oxidation potential represents the ease with which a species can be oxidized, or lose electrons. Conversely, reduction potential indicates how readily a species gains electrons, undergoing reduction. Both potentials are measured in volts and signify a substance's electron transfer capability.

In the context of electrochemistry, oxidation potential reflects the propensity of a substance to act as an oxidizing agent, donating electrons. Reduction potential, on the other hand, measures a substance's ability to function as a reducing agent by accepting electrons.

The oxidation potential is often considered in terms of positive values, where higher values indicate stronger oxidizing agents. In contrast, reduction potential is typically associated with negative values for strong reducing agents, although it can be positive too.
