Oxidation-Reduction Reactions Chemistry for Non

The pure metals can be extracted by reduction. Iron is obtained from iron(III) oxide by reacting with carbon at high temperatures. The removal of oxygen from the Fe 2 O 3 means that it is being reduced to Fe. Note that an oxidation process is simultaneously occurring. The carbon reactant is being oxidized to CO 2 . This is an important concept.
