Redox potential definition

the standard potential of an atom or ion that undergoes oxidation at the anode or reduction at the cathode in an electrochemical cell as compared to the potential of a standard hydrogen electrode when it is undergoing the same process —called also redox potential…. See the full definition..

Updated on September 03, 2019. The standard reduction potential is the potential in volts generated by a reduction half-reaction compared to the standard hydrogen electrode at 25 °C, 1 atm and a concentration of 1 M. The standard reduction potential is defined relative to a standard hydrogen electrode, which is assigned the potential 0.00 V.Electrochemistry Basics. Electrochemistry is the study of chemical processes that cause electrons to move. This movement of electrons is called electricity, which can be generated by movements of electrons from one element to another in a reaction known as an oxidation-reduction ("redox") reaction.Define : Standard electrode potential.

Biology definition: Biological oxidation is a biological process that involves the loss of electrons as opposed to the reduction process where there is a gain of electrons. Oxidation and reduction, however, are coupled together as a ‘redox ‘ reaction, which is an energy-producing reaction within the cell.ORP (Oxidation-Reduction Potential) is the measurement, in millivolts, of a solution's capacity for electron transfer (oxidation or reduction). ORP measurement may also be called REDOX for REDuction OXidation. The name reflects that fact that within a chemical reaction reduction and oxidation are complementary; one cannot occur without the other.

As for other thermodynamic quantities, the standard cell potential, E°cell, is a cell potential measured when both half-cells are under standard-state conditions (1 M concentrations, 1 bar pressures, 298 K): E∘ cell =E∘ cathode −E∘ anode E cell ∘ = E cathode ∘ − E anode ∘.
