General Information

 H2O2 is a colorless and odorless liquid chemical formula, soluble in water and alcohol, depending on the environment, reducing and oxidizing properties, chemically unstable, dense liquid in the form of a chemical. It can easily decompose to give water and oxygen. H2O2 solutions in the range of 70-90% can show explosive properties. In cases where the metal impurity exhibits catalytic effect, the rate of deterioration of this substance is increasing.

 Production and Reactions

Hydrogen peroxide is found in nature in snow and rain. In old times, barium oxide was obtained from the treatment of barium peroxide with sulphate acid obtained by heating the air to 500 ° C in the air.

 BaO2 H2SO 4 - 4 BaSO 4 H2O 2
Occurs around the cathode during the electrolysis of water. Ethyl is obtained from the autoxidation of the anthraquinone. When the concentrated sulfate acid is electrolyzed, the peroxydisulphate acid is obtained. Hydrogen peroxide can be obtained from the reaction of the substance formed as a secondary reaction with water.

H2S2O 8 2H2O - - 2H2SO4 H2O2

Usage areas
