Reduction potential meaning
Oxidation-reduction potential (ORP) or redox is a measurement that indicates how oxidizing or reducing a liquid is. For example, water may be moderately oxidizing (such as aerated water), strongly oxidizing (such as chlorinated water or hydrogen peroxide solution), or reducing (such as an environment where anaerobic microbes are active).
What does a more negative reduction potential mean? A solution with a greater (more positive) reduction potential than the new species will tend to receive electrons from the new species (i.e., to be reduced by oxidizing the new species) and a solution with a lower (more negative) reduction potential will tend to lose electrons to the new species.
The reduction potential is a measure of the tendency of the oxidizing agent to be reduced. Its value is zero for H + + e − → 1 ⁄ 2 H 2 by definition, positive for oxidizing agents stronger than H + (e.g., +2.866 V for F 2) and negative for oxidizing agents that are weaker than H + (e.g., −0.763 V for Zn 2+).: 873And we've done this several times. When you reverse a reduction half-reaction and turn it into an oxidation half-reaction which is what we've done down here, you just change the sign on the standard reduction potential. So the standard reduction potential is negative 1.66 volts, all we have to do is change the sign, so it's positive 1.66 volts.Aug 29, 2023 · Given: reduction half-reaction, standard electrode potential, and list of possible reductants.
