What is one Oxidizing Agent?

An oxidizing agent (often referred to as an oxidizer or an oxidant) is a chemical varieties that often tends to oxidize various other substances, i.e. Cause an increase in the oxidation state that the substance by making it lose electrons. Common examples the oxidizing agents include halogens (such as chlorine and fluorine), oxygen, and hydrogen peroxide (H2O2).

Oxidizing agents deserve to be defined in two various ways:

As an electron acceptor – They space chemical substances whose atoms eliminate at the very least one electron from one more atom in a chemical reaction. Together per this definition, oxidizing agents room the reactants the undergo reduction in oxidization reactions. An illustration detailing the electron-accepting nature of oxidizing agents is provided below.


Here, problem ‘A’ undergoes oxidation, result in boost in the oxidation number. Top top the other hand, the oxidation state of substance ‘B’ becomes smaller sized (since it gains electron by experience reduction).

As an atom-transferring substance – one oxidizing agent is a substance that transfers at least one electronegative atom come a chemical species in a chemistry reaction. The moved atom is frequently an oxygen atom. Several burning reactions and organic redox reaction involve the transfer of an electronegative atom in between two reactants.


In the example illustrated above, the Fe2O3 molecule acts as an oxidizer by moving an electronegative oxygen atom come the carbon monoxide molecule.

What Factors influence the Oxidizing strength of one Oxidizing Agent?

Oxidizing agents typically exist in your highest possible oxidation states and, therefore, have a solid tendency to get electrons and undergo reduction. Ions, Atoms, and also molecules having actually a strong affinity in the direction of electrons are taken into consideration to be good oxidizers. The stronger the electron affinity, the better the oxidizing power.

Elemental fluorine is stated to it is in the strongest elemental oxidizing agent. This is perhaps because of the truth that fluorine is the many electronegative aspect in the modern-day periodic table, and also therefore exerts the the strongest attractive pressure on electrons among all the elements. In fact, the oxidizing power of diatomic fluorine (F2) is solid enough to reason metals such as asbestos and quartz (and also molecules, such together water) to burst into flames when exposed to it.

A couple of other instances of elemental oxidizing agents encompass diatomic oxygen (O2), diatomic chlorine (Cl2), and ozone (O3). These oxidizers space the elemental forms of the 2nd and the third most electronegative facets (oxygen and chlorine respectively), make them great electron acceptors.

The typical electrode potential of a half-reaction in a redox process provides insight into the oxidizing strength of the chemical substance. One illustration ranking some oxidizers in regards to their oxidizing powers is provided below.


Some compounds that exhibit huge oxidation states can additionally be considered an excellent oxidizing agents. Ionic examples include the permanganate ion, the chromate ion, and also the dichromate ion. Acidic examples of good oxidizers include nitric acid, perchloric acid, and also sulphuric acid. The electronegativity of the molecules increases with the increase in the oxidation says of the atoms, enhancing their capacity to oxidize various other substances.

Examples the Oxidizing Agents


The group 17 aspects of the regular table are jointly referred to as Halogens. They are claimed to have a strong ability to obtain electrons, meeting to your high electronegativities when compared to facets from various other groups. This means that they have the capacity to easily attract electrons towards their particular nuclei. Instances of the halogens that are great oxidizing agents include iodine, bromine, chlorine, and also fluorine. Fluorine is said to be the the strongest elemental oxidizing agent due to its highest possible electronegativity, as debated earlier.


Oxygen is the facet corresponding come the atomic number 8 and is denoted by the price ‘O’. It belongs come the chalcogen group of the periodic table and is a extremely reactive non- metal with an excellent oxidizing properties. In general, metals tend to form metal oxides by reacting with atmospheric oxygen, as result of the strong oxidizing power of oxygen. Oxygen is observed to it is in a component of a majority of combustion reactions.

Hydrogen Peroxide

Hydrogen peroxide is the chemical compound having actually formula H2O2. It appears to the human eye as a colourless liquid which has a better viscosity than water. Hydrogen peroxide is the easiest compound having actually a peroxide functional group with an oxygen-oxygen solitary bond. It finds its provides as a weak oxidizing agent, disinfectant, and a bleaching agent.

Many other oxidizing agents are frequently used industrially and in the day-to-day lives of humans. Examples incorporate household bleach (NaClO), Potassium Nitrate (KNO3), and also Sulphuric mountain (H2SO4).

What are the Applications of Oxidizing Agents?

Oxidizing agents have plenty of commercial and industrial applications. A couple of of these applications are noted below.

Bleaching the fabrics.Purification that water.Combustion the fuel requires the usage of an oxidizing agent.Storage of energy in batteries.Vulcanization the rubber (increasing the strength and the elasticity that rubber).Oxidizing agents room also crucial to many organic processes such together metabolism and also photosynthesis.
