Important Differences between Hydrogen peroxide and Rubbing alcohol

Hydrogen peroxide

Hydrogen peroxide (H2O2) is a chemical compound consisting of two hydrogen atoms and two oxygen atoms, arranged in a diatomic molecule. It is a pale blue liquid with strong oxidizing properties, commonly used as a disinfectant, bleach, and cleaning agent. Hydrogen peroxide is notable for its ability to decompose into water and oxygen, making it an eco-friendly option. In various concentrations, it serves as a hair bleach, wound antiseptic, and industrial oxidizer. While beneficial in certain applications, concentrated hydrogen peroxide can be corrosive and should be handled with care due to its potential reactivity and the release of oxygen during decomposition.

Rubbing alcohol

Rubbing alcohol, commonly known as isopropyl alcohol (IPA), is a colorless and flammable chemical compound with the molecular formula C3H8O. It is a secondary alcohol, featuring a hydroxyl group on a carbon atom adjacent to two methyl groups. Isopropyl alcohol is widely used as a disinfectant, antiseptic, and cleaning agent due to its ability to kill bacteria and viruses. It evaporates quickly, leaving surfaces dry and free of residue. Additionally, it serves as a solvent in various applications, including the production of cosmetics, pharmaceuticals, and personal care products. Rubbing alcohol is a versatile solution with antiseptic properties, making it a staple in medical, household, and industrial settings.

• Melting Point:

Exhibits a freezing point around -89 degrees Celsius (-128 degrees Fahrenheit).

• Density:

Has a density of about 0.785 grams per cubic centimeter.

• Solubility:

Miscible in water and many organic solvents.

• Vapor Pressure:

Generates a significant vapor pressure at room temperature.

Chemical Properties of Rubbing Alcohol (Isopropyl Alcohol):
