What is hydrogen peroxide and used for

Hydrogen peroxide (H2O2) is a chemical compound made up of two hydrogen atoms and two oxygen atoms. It is a clear and colorless liquid with a slightly bitter taste. Hydrogen peroxide is a powerful oxidizing agent, and its chemical structure is often represented as H-O-O-H, highlighting its peroxide bond.

Hydrogen peroxide has many uses, including:

  • Disinfectant: Hydrogen peroxide is commonly used as an antiseptic to clean wounds and disinfect surfaces. When applied to minor cuts and abrasions, it can help kill bacteria and prevent infection.

  • Bleaching agent: It is used as bleach for hair and clothes. In the fashion industry, it is sometimes used to create a distressed or "bleached" look on denim and other fabrics.

  • Teeth whitening: Some toothpaste and mouthwash products contain hydrogen peroxide as a teeth whitening agent.

  • Hair coloring: It is used in some hair dyes to lighten or bleach hair.

  • Cleaning Agent: Hydrogen peroxide is an effective household cleaner for removing stains, mold and mildew. It can also be used to clean and disinfect kitchen and bathroom surfaces.

  • Rocket Propellant: In high-concentration, high-purity forms, hydrogen peroxide has been used as a propellant in rocket engines.

  • Environmental Applications: In some environmental applications, it is used to treat water and soil contaminants.

  • Chemical Synthesis: Hydrogen peroxide is used as a reactant in a variety of chemical reactions and processes, including the production of other chemicals.

Hydrogen peroxide is available in various concentrations, with different uses depending on the strength. Low concentrations (about 3%) are typically used for household and personal care applications, while higher concentrations are used in industrial and scientific processes. It is important to handle hydrogen peroxide with care, as it can be corrosive and potentially harmful if not used properly.
