Oxidation-Reduction Potentials. One way to quantify whether a substance is a strong oxidizing agent or a strong reducing agent is to use the oxidation-reduction potential or redox potential. Strong reducing agents can be said to have a high electron-transfer potential. Strong oxidizing agents have low electron-transfer potential.The values of standard redox potential (E ∘) of two half-cell reactions decide which way the reaction is expected to proceed. A simple example is a Daniel cell in which zinc goes into solution and copper gets deposited.The reason for this becomes clear when we look at the standard reduction potentials (E°) and calculate the oxidation-reduction potential (ORP). The sum of the half reaction potentials, 0.76 and 0.34 V, gives an ORP of 1.10 V in standard conditions. Because 1.10 V is positive, this indicates that the reaction is favorable and occurs spontaneously.The distance that the electron falls is the same regardless of the number of electrons that fall. A reduction potential reflects an inherent property of the material and does not depend on how many electrons are being transferred. Reduction potentials reflect the energy difference between two states.More the negative reduction potential, more is the tendency to lose electron or electrons. Thus reducing nature decreases from top to bottom in the electrochemical series. The power of the reducing agent increases (ability to reduce), as the standard reduction potential becomes more and more negative. 4.Reduction involves a gain of electrons, and so, the electrode tendency to gain electrons is referred to as its reduction potential.
