WebRedox (kortform för reduktion-oxidation -reaktion) är det kemiska fenomen vid vilket oxidationstalen hos atomer förändras. Vanligtvis sker detta genom att en eller flera elektroner förflyttas från en atom till en annan. Oxidation är fenomenet att en atom, molekyl eller jon avger en eller flera elektroner. Oxidationstalet stiger.
Redox potential (also known as oxidation / reduction potential, ORP, pe, $${\displaystyle E_{red}}$$, or $${\displaystyle E_{h}}$$) is a measure of the tendency of a chemical species to acquire electrons from or lose electrons to an electrode and thereby be reduced or oxidised respectively.
