Standard reduction potential (also known as redox potential, oxidation / reduction potential or ORP) is the tendency of a chemical species to acquire electrons and thereby be reduced. Each species has its own intrinsic reduction potential; the more positive the potential, the greater the species' affinity for electrons and tendency to be reduced.Basically a signal is sent between them which determines your oxidation and reduction potential. The rate of electron transfer is measured in mV and read as ORP. The higher, the better, and most health departments in the United States recognize 650mV as the minimum acceptable ORP, and if you can get over 800mV that's great.That is because chemical reactivity of metals decrease as reduction potential decreases.

The ORP value, much like pH, is ... Electrode Reduction and Oxidation Potential . Corrosion, the degradation of metals as a result of electrochemical activity, requires an anode and a cathode in order to occur. The anode is the metal or site with a higher potential to oxidize (lose electrons) while the cathode is the metal or site with a higher potential for reduction (gaining of electrons).Remember the potential is with respect to a reference electrode, and positive/negative connotation here simply means more negative--cathodic--reduction at the working electrode or cathode.Mar 19, 2020 · Does higher reduction potential mean more likely to be reduced?
