Step-by-step explanation:
An oxidizer is a substance that facilitates oxidation, a chemical reaction where a substance loses electrons. It is also called an oxidizing agent or oxidant. Oxidizers are commonly used in combustion reactions, supporting the burning of fuels by providing oxygen. Examples of oxidizers include oxygen, chlorine, hydrogen peroxide, and potassium permanganate. They have applications in combustion, chemical synthesis, bleaching, rocket propellants, and cleaning. Oxidizers can be highly reactive and require proper handling and safety precautions.
