    If the value of standard electrode potential is negative, this signifies the redox couple is the stronger reducing agent in comparison to H + /H 2 couple. Similarly, a positive standard electrode potential signifies that the redox couple is a weaker reducing agent in comparison to H + /H 2 couple. Application Note #74 – Oxidation-Reduction (Redox) Potential Updated July 2017 . Introduction: Oxidation-reduction potential (ORP), also known as redox potential, refers to the capacity of a solution to oxidize (accept electrons) or reduce (donate electrons) 1.

    Redox indicators. Characteristics and applications 467 Because of difuioultiea concerning the rigoroue definition for formal. re.. dox potential a more praotioal term used in this report in parallel is ha1foxidationpotential, Transition potential is often given instead of the formal redox potential. the irreversibility or mechanistic complexity of redox reactions can make the direct experimental measurement of a corresponding reduction potential difficult. For this reason, computational chemistry offers a valuable alternative to experiment for the characterization of redox reactions.
