Hydrogen peroxide (H2O2) is a clear,
colorless liquid that is commonly used as a bleaching agent, disinfectant, and
oxidizer in various industrial, medical, and household applications.
Here are the details of Hydrogen Peroxide along with its CAS number:

proportions.
Hydrogen peroxide is composed of two hydrogen atoms and two oxygen atoms and is structurally similar to water (H2O), but with an additional oxygen atom. It is a weak acid and is slightly more viscous than water.
Here are some common uses of Hydrogen Peroxide:
1. Disinfectant and Antiseptic: Hydrogen peroxide is used as a disinfectant and antiseptic to clean and disinfect wounds, cuts, and minor injuries. It helps to kill bacteria, viruses, and fungi by releasing oxygen and producing reactive oxygen species.
2. Bleaching Agent: Hydrogen peroxide is used as a bleaching agent in the textile, paper, and pulp industries to whiten and brighten fabrics, paper products, and wood pulp. It is also used in hair bleaching products to lighten hair color.
3. Oxidizer: Hydrogen peroxide is used as an oxidizing agent in various chemical processes, including the production of organic and inorganic chemicals, as well as in environmental remediation to degrade and detoxify organic pollutants.
4. Water Treatment: Hydrogen peroxide is used in water treatment processes to remove organic contaminants, odors, and taste compounds from drinking water and wastewater. It helps to oxidize and decompose organic compounds, as well as to disinfect water.
5. Cosmetics and Personal Care Products: Hydrogen peroxide is used in cosmetics and personal care products, such as toothpaste, mouthwash, and hair care products, for its antiseptic and bleaching properties.
6. Laboratory and Pharmaceutical Applications: Hydrogen peroxide is used in laboratories and pharmaceutical manufacturing processes for cleaning and sterilizing equipment, as well as in chemical synthesis and analysis.
Hydrogen peroxide is valued for its effectiveness as a disinfectant, bleaching agent, and oxidizer, as well as its relatively low toxicity compared to other disinfectants and oxidizing agents. However, it should be handled with care, as concentrated hydrogen peroxide can be corrosive and may cause irritation or burns on contact with skin or mucous membranes. Diluted solutions of hydrogen peroxide are commonly available for household and medical use.
