What is the reduction potential.

Oxidation Reduction Potential (ORP) is a measurement of sanitizer effectiveness in water. ORP is an electronic measurement-in millivolts (mV)-of the ability of a chemical substance to oxidize or reduce another chemical substance. Both oxidation and reduction are chemical processes involving the transfer of electrons between molecules ...Reduction potential, also known as redox potential, is a measure of the tendency of a chemical species to acquire electrons and thereby be reduced. It is expressed in volts (V), or millivolts (mV). 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.As seniors enter retirement, managing finances becomes a top priority.

The equilibrium potential difference between the metal electrode and the solution surrounding it is called the electrode potential. It is also defined as the tendency of an electrode to lose or gain electrons.

An example would be ½ O2/H2O, where H2O could serve as an electron donor and O2 could serve as an electron acceptor. Each half reaction is given a standard reduction potential (E’0) in volts or millivolts, which is a measurement of the tendency of the donor in the reaction to give up electrons. A substance with greater tendency to donate ...Oxidation Reduction Potential (ORP or REDOX Potential) measures an aqueous system’s capacity to either release or accept electrons from chemical reactions.
