hydrogen peroxide can be used to treat not only the mechanical damage to the skin - small wounds and cuts.In the past 3 percent solution of the substance used for the treatment of pneumonia, and various viral STI diseases.Prior to the discovery of penicillin peroxide was administered intravenously to people with lung diseases and bronhov.V nowadays feasibility of such an application hydrogen peroxide contested.Some experts agree that this practice has brought positive results, while others argue that hydrogen peroxide for oral administration is not suitable.However, its external application is still ongoing.

To make a 3-percent solution hydrogen peroxide , initially a concentrated solution of its .The easiest way to obtain it in the laboratory - the use of met
al oxides on exposure to a dilute sulfuric acid.Thus, for example, barium oxide in cold conditions, connecting with sulfuric acid, forms peroxide hydrogen and salt - barium sulfate: BaO2 + H2SO4 = H2O2 + BaSO4 In industry, sulfuric acid is produced by electrolysis of sulfuric acid, followed by hydrolysis of persulfuric acid:2H2SO4 = H2S2O8 + 2H + + 2e-, H2S2O8 + 2H2O = 2H2SO4 + H2O2 Also hydrogen peroxide obtained by oxidation of isopropanol.It is formed in nature - by the oxidation of various substances with oxygen.Furthermore, in low concentrations it is found in animal cells.

After a concentrated solution hydrogen peroxide , cook out of it 3-percent solution .To do this, take the enamel bowl, pour into it the water tempera- about 50 degrees, then add the hydrogen peroxide the appropriate kolichestve.Perekis hydrogen, in addition to its medical devices are also used in industry.For example, it is used for the bleaching of textiles and paper.Also, it is a good disinfectant in the food industry.Hydrogen peroxide - bleaches, so it has been widely used in cosmetology.
