Content

Oxidizing and reducing agents

• Oxidizing agents give oxygen to another substance.
• Reducing agents remove oxygen from another substance.

For example the extraction of iron from its ore

Fe2O3 + 3CO ----à 2Fe + 3CO2

Fe2O3 ----à 2Fe   oxidizing agent

3CO -------à 3C02 reducing agent

An oxidizing agent is a substance which oxidizes something else. In the above example, the iron(III) oxide is the oxidizing agent. A reducing agent reduces something else. In the equation,…
