WebOxidation–reduction reactions, commonly known as redox reactions, are reactions that involve the transfer of electrons from one species to another. The species that loses electrons is said to be oxidized, while the species that gains electrons is said to be reduced. We can identify redox reactions using oxidation numbers, which are assigned ... Consider the following reaction: 2 [Fe(CN)6] + Cl 2 → 2 [Fe(CN)6] + 2 Cl The reducing agent in this reaction is ferrocyanide ([Fe(CN)6] ). It donates an electron, becoming oxidized to ferricyanide ([Fe(CN)6] ). Simultaneously, that electron is received by the oxidizer chlorine (Cl 2), which is reduced to chloride (Cl ).
