What is oxidation reduction potential
An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species.

Redox reactions are common and vital to some of the basic ...The redox potential, or more accurately the reduction potential, of a compound refers to its tendency to acquire electrons and thereby to be reduced. Some readers might remember the mnemonic “OILRIG” which reminds us that “oxidation is loss, reduction is gain”, where the loss and gain are of electrons. Consider a reaction that involves ...

Redox quickly falls to 0.2 volt or less at a depth of a few millimeters into the sediment because of oxygen-depletion resulting from microbial activity. The redox potential also falls quickly in sediment even in nutrient-poor (oligotrophic) lakes. However, the sediment depth for a redox of 0.2 volt may be 5 to 10 cm below the soil-water ...Oxidation - Reduction (cross reference with section 4.1 page 165 Wiedemeyer) Oxidation-reduction reactions are commonly referred to as "redox" reactions.

For example, from this table we can find the substance that is easiest to reduce. That is at the the top of the table (the F 2 /2F-redox couple). ALL the substances on the left are being reduced but the reactions become less and less likely as the potential goes from positive to negative. Contrary to this are the substances that are being oxidized.some atomic unit in the species to be reduced. Oxidationreduction potential (ORP) or redox - potential (hereafter, referred to as redox) is a measure of the intensity or activity of an aqueous environment or soil to mediate reactions of important elements in biological systems (e.g., O, N, Mn, Fe, S, and C) and other metallic elements.Figure 1. A generic redox reaction. The full reaction is A +B goes to A+ + B-. The two half reactions are shown in the blue box. A is oxidized by the reaction and B is reduced by the reaction. When an electron (s) is lost, or a molecule is oxidized, the electron (s) must then passed to another molecule.As the oxidation-reduction potential (ORP) and the speed of the reduction reaction are closely tied to the pH value, ORP and pH meters are used to ensure proper control of the reduction process through such means as the injection of reducing agents. For more detailed information we can send you the application note that we have on Chrome reduction.Oxidation potential = - Reduction potential For example, in a zinc electrode, the standard oxidation potential is represented as Eo (Zn/Zn2+) = 0.76V and standard reduction potential as Eo (Zn2+/Zn) = -0.76V It is a common practice to express all the electrode potentials as reduction potentials.
