The aqueous solution is colorless and transparent liquid, soluble in water and alcohol. Pure hydrogen peroxide is a pale blue viscous liquid.

Pure hydrogen peroxide is a light blue viscous liquid with a melting point of -0.43 °C and a boiling point of 150.2 °C. The solid density is 1.71g/cm3 at the freezing point, and the density decreases with the increase of temperature. It is more associative than H2O, so its dielectric constant and boiling point are higher than water. Pure hydrogen peroxide is relatively stable and violently decomposes into water and oxygen when heated to 153 °C.

Hydrogen peroxide, scientific name hydrogen peroxide, is a colorless transparent liquid, soluble in water, alcohol and ether, corrosive at high concentration, and gradually decomposes into oxygen and water when placed. The density of hydrogen peroxide is 1.11g/cm3, the melting point is -0.89, and the boiling point is 151.4. Molecular formula H2O2, molecular weight: 34.01. Ordinary industrial-grade hydrogen peroxide contains a large amount of anthraquinone organic impurities as well as anions and cations, mechanical impurities, etc. These toxic and harmful impurities will seriously affect the application of hydrogen peroxide in certain industries, such as electronics, electroplating, chemical synthesis and other fields. High-purity hydrogen peroxide uses special methods to purify and remove impurities. It is a high-quality, pure hydrogen peroxide, so it can be widely used in all high-demand occasions.

The uses of hydrogen peroxide are divided into three types: medical, military and industrial. Daily disinfection is medical hydrogen peroxide. Medical hydrogen peroxide can kill intestinal pathogens, pyogenic cocci, and pathogenic yeasts. It is generally used for surface disinfection. Hydrogen peroxide has an oxidizing effect, but the concentration of medical hydrogen peroxide is equal to or lower than 3%. If it is wiped on the wound surface, there will be a burning sensation, the surface will be oxidized into white and bubbles will appear. Restores original complexion.

In the chemical industry, it is used as a raw material for the production of sodium perborate, sodium percarbonate, peracetic acid, sodium chlorite, thiourea peroxide, etc., and an oxidant for tartaric acid, vitamins, etc. In the pharmaceutical industry, it is used as a fungicide, a disinfectant, and an oxidant in the production of Fomex insecticides and 40l antibacterial agents. In the printing and dyeing industry, it is used as a bleaching agent for cotton fabrics and a color-forming agent after vat dyeing. Removal of iron and other heavy metals when used in the production of metal salts or other compounds. It is also used in electroplating solution to remove inorganic impurities and improve the quality of plated parts. Also used for bleaching wool, raw silk, fur, feathers, ivory, bristles, pulp, fat, etc. High concentrations of hydrogen peroxide can be used as rocket power fuel.
