Before entering fully into the definition of the term oxidizer, we are going to proceed to know what its etymological origin is. In this case, we can determine that it is a word that derives from Latin, exactly from “comburentis” which can be translated as “that causes it to ignite”. Latin word that is the result of the sum of three clearly differentiated elements:
-The prefix “with”, which is equivalent to “all” or “together”.
-The verb “burere”, which is synonymous with “burn”.
-The suffix “-nte”, which is used to indicate “agent”.

A oxidizer is a substance that generates the development of combustion.

OxidizingCombustion is the act and result of burning (to subject to fire). At the chemical level, combustion involves the oxidation of a substance through a process in which energy is released by way of light and heat. This reaction is generated between an oxidizable material capable of burning, which is called fuel, and a material that produces combustion, called oxidizer.

The oxidizer causes the fuel to rust, releasing chemical energy that can be harnessed as mechanical energy. For combustion to start, the fuel must reach its ignition temperature (when its vapors burn spontaneously). It should be noted that the reaction between the fuel and the oxidizer is manifested through the calls.

Because it is responsible for oxidizing another substance, the oxidizer is also called oxidizing agent. In the reduction-oxidation reaction (redox), the oxidizer gains electrons by reducing it, while the reducing agent (the fuel in a combustion process) loses electrons by oxidizing.

The oxygen it is the most common oxidizer. A minimum of oxygen is required in all combustion processes, which can appear in a gaseous or liquid state. A firearm that uses gunpowder, for example, may use the salt of an oxyacid (such as potassium chlorate) in the cartridge to achieve the combustion that allows the projectile to fire.

Although oxygen is the quintessential oxidizer, we cannot ignore the existence of others that are very relevant. We are referring to some as the following:
-Nitrates, among which lithium nitrate, silver nitrate, ammonium nitrate or sodium nitrate stand out, for example.
-Chlorates, such as copper chlorate, magnesium chlorate or calcium chlorate.
-Permanganates, such as zinc permanganate, potassium permanganate or calcium permanganate.
-Organic peroxides: acetylacetone peroxide, tert-butyl peroxyacetate and tert-butyl monoperoximaleate.

There is a list of oxidizers in which peroxics, halogens, ozone, nitric acid, perchlorates, chlorites or chromic acid should not be overlooked, among many others that can also be used for promote combustion.
