Hydrogen peroxide (H₂O₂) is a colorless liquid chemical compound with a slightly pungent odor. It is a common household chemical and has various industrial and medicinal uses.
Chemical Properties:
- Molecular Structure: It consists of two hydrogen atoms and two oxygen atoms bonded together. The oxygen atoms are linked by a single bond, and each oxygen atom is also bonded to a hydrogen atom.
- Oxidizing Agent: Hydrogen peroxide is a powerful oxidizing agent, meaning it readily donates oxygen atoms to other substances. This property is responsible for many of its uses, such as bleaching and disinfection.
- Decomposition: It is unstable and readily decomposes into water (H₂O) and oxygen gas (O₂) especially in the presence of catalysts like metals, metal ions, or light. This decomposition releases heat.
- Acidic Nature: It is a weak acid.
- Solubility: It is miscible with water, alcohol, and ether.
Common Uses:
- Antiseptic: It is used as a mild antiseptic to clean minor cuts, scrapes, and burns to prevent infection.
- Mouthwash: It can be used as a mouth rinse to help remove mucus and relieve minor mouth irritation.
- Teeth Whitening: It is an active ingredient in many over-the-counter and professional teeth whitening products.
- Hair Bleaching/Lightening: It is used to lighten hair color.
- Cleaning and Disinfecting: It is used as a household cleaner and disinfectant for surfaces, laundry, and even food.
- Stain Removal: It can effectively remove various stains like blood, wine, and grass.
- Industrial Uses: In higher concentrations, it is used as a bleaching agent for textiles and paper pulp, in chemical manufacturing, wastewater treatment, and even as a rocket propellant.
Safety Precautions:
- Concentrated hydrogen peroxide can be corrosive and cause burns to the skin and eyes.
- Ingestion of high concentrations can be dangerous.
- It should be stored in a cool, dark place away from heat and incompatible materials to prevent decomposition.
- Always follow the instructions and safety guidelines on the product label.
