WebVanadium's oxidation states. Vanadium has oxidation states in its compounds of +5, +4, +3 and +2. This section looks at ways of changing between them. It starts with a bit of description, and then goes on to look at the reactions in terms of standard redox potentials (standard electrode potentials). Observing the changes in the lab WebRedox reactions are oxidation-reduction chemical reactions in which the oxidation states of the reactants change. The term ‘redox’ is an abbreviation for reduction-oxidation. All redox reactions can be divided into two types of processes: reduction and oxidation.
