Hydrogen peroxide (H2O2) is a clear, colorless liquid that is chemically composed of two hydrogen atoms and two oxygen atoms. It is a powerful oxidizing agent and is commonly used for a wide range of applications. Hydrogen peroxide is perhaps best known for its use as an antiseptic and disinfectant. It is used to clean and disinfect wounds, surfaces, and various medical equipment. The effervescence produced when hydrogen peroxide comes into contact with organic material helps in the removal of debris and potential pathogens.

Beyond its medical uses, hydrogen peroxide has many industrial applications. It is utilized in the paper and textile industries as a bleaching agent to whiten pulp and fabric. In the food industry, it is employed as a sterilizing agent for packaging materials and equipment. Hydrogen peroxide is also used in the production of electronics, as a propellant in rocketry, and in environmental applications for wastewater treatment. Its ability to break down into water and oxygen makes it an environmentally friendly choice for many applications, and its versatility and effectiveness make it a valuable chemical compound in various industries.
