Oxidation-reduction potential (ORP, redox) measures the rate of oxidative disinfection caused by the addition of the effects of all oxidants in the pool water. ORP is determined by using a high quality ORP probe and meter. The unit of measurement of ORP is millivolts (mV). Potential Eo (V) Li+ (aq) + e-→ Li (s) -3.0401 Cs+ (aq) + e-→ Cs (s) -3.026 Rb+ (aq) + e-→ Rb (s) -2.98 K+-(aq) + e → K (s) -2.931 Ba2+ (aq) + 2 e-→ Ba (s) -2.912 Sr2+ (aq) + 2 e-→ Sr (s) -2.89 Ca2+ (aq) + 2 e-→ Ca (s) -2.868 Na+-(aq) + e → Na (s) -2.71 Mg2+-(aq) + 2 e → Mg (s) -2.372 Al3+ (aq) + 3 e-→ Al (s) -1.662 A redox potential is the potential value when the reduction and oxidation of a certain metal or other chemical are in balance with each other. Redox potential is measured in Volt (V). Redox potential values (under certain standard conditions) are fixed and can be found in tables like this one.

• The potential is measured at the point that there is no net flow of electrons. Defining standard electrode potential (standard redox potential) The values that we have just quoted for the two cells are actually the standard electrode potentials of the Mg 2+ / Mg and Cu 2+ / Cu systems. biochemically relevant redox potentials ^ a b Not specified in the indicated reference, but assumed due to the difference between the value −0.454 and that computed by (2×(−0.499) + (−0.508))/3 = −0.502, exactly matching the difference between the values for white (−0.063) and red (−0.111) phosphorus in equilibrium with PH 3 .

Redox potential is used as: An indicator of electrochemical reactivity of substances in environmental conditions For predicting corrosion protection of various substances and systems Redox potential, also known as standard electrode potential, is a measure of how easily a substance loses or gains electrons in a reduction- oxidation — or “redox” — reaction, a chemical reaction where one reactant is reduced and the other oxidized.
