This page discusses what defines an oxidizing or reducing agent, how to determine an oxidizing and reducing agent in a chemical reaction, and the importance of this concept in real world applications.
This chemistry video explains how to find the oxidizing agent and the reducing agent in a redox reaction. It explains how to determine which reactant is oxidized and which substance is reduced.
An oxidizing agent (often referred to as an oxidizer or an oxidant) is a chemical species that tends to oxidize other substances, i.e. cause an increase in the oxidation state of the substance by making it lose electrons. Common examples of oxidizing agents include halogens (such as chlorine and fluorine), oxygen, and hydrogen peroxide (H 2 O 2).
For example, identify the oxidizing and reducing agent, the element that is oxidized, and the element that is reduced in the following redox reaction: 2KMnO 4 + 16HCl → 2MnCl 2 + 5Cl 2 + 2KCl + 8H 2 O. Remember, not all the atoms undergo oxidation or reduction in a redox reaction.
Summary. An oxidizing agent is a substance that causes oxidation by accepting electrons; therefore, it gets reduced. A reducing agent is a substance that causes reduction by losing electrons; therefore it gets oxidized. Examples of how to identify oxidizing and reducing agents are shown.
This video tutorial shows you how to identify the oxidizing and reducing agent in a redox reaction.
The simplest way to think of this is that the oxidizing agent is the substance that is reduced, while the reducing agent is the substance that is oxidized. The example below shows how to analyze a redox reaction.

The permanganate ion removes electrons from oxalic acid molecules and thereby oxidizes the oxalic acid. Thus, the MnO 4- ion acts as an oxidizing agent in this reaction. Oxalic acid, on the other hand, is a reducing agent in this reaction.
How to Find Oxidizing Agent. In order to find the oxidizing agent in a chemical reaction, we need to look at the compound's oxidation state at the beginning and end of the reaction.
