Answer:

Oxidation states simplify the process of determining what is being oxidized and what is being reduced in redox reactions. However, for the purposes of this introduction, it would be useful to review and be familiar with the following concepts:

oxidation and reduction in terms of electron transfer

electron-half-equations

To illustrate this concept, consider the element vanadium, which forms a number of different ions (e.g., V2+ and V3+ ). The 2+ ion will be formed from vanadium metal by oxidizing the metal and removing two electrons:

V→V2++2e−(1)

The vanadium in the V2+ ion has an oxidation state of +2. Removal of another electron gives the V3+ ion:

V2+→V3++e−(2)

The vanadium in the V3+ ion has an oxidation state of +3. Removal of another electron forms the ion VO+2 :

V3++H2O→VO2++2H++e−(3)

The vanadium in the VO2+ is now in an oxidation state of +4.
