Hydrogen peroxide (hydrogen peroxide), is an inorganic compound, chemical formula H ₂ O ₂, relative molecular mass of 34.02, colourless liquid, relative density of 1.465g/cm ³, melting point -1 ° C, boiling point of 150.2 ° C, the pure article is easy to decomposition of water and oxygen, commercially available for 30% or 3% of the aqueous solution, the more stable in the dark, see the light or meet the impurity will accelerate the decomposition. Decomposition, a small amount of acid, sodium stannate, sodium pyrophosphate, ethanol, acetanilide or acetoethoxyaniline can increase its stability.

Physical and chemical properties

1. Appearance: colorless transparent liquid.

2. Chemical properties: under normal circumstances, it will be slowly decomposed into water and oxygen, but the decomposition speed is extremely slow. The way to accelerate the reaction speed is to add manganese dioxide catalyst or irradiation with short wave radiation.

3. Solubility: Water solution is a colorless transparent liquid, soluble in water, alcohol, ether, insoluble in benzene, petroleum ether.

4. Hydrogen peroxide has a strong oxidation effect on organic matter, and is generally used as an oxidant.

Hydrogen peroxide applications

1. Medical hydrogen peroxide can kill intestinal pathogenic bacteria, suppurative coccus, pathogenic yeast, generally used for surface disinfection.

2. Chemical industry used for the production of sodium perborate, sodium percarbonate, peracetic acid, sodium chlorite, thiourea peroxide and other raw materials, tartric acid, vitamins and other oxidants.
