Hydrogen peroxide is produced by the immune system, but in a carefully controlled manner. Cells called phagocytes engulf pathogens and then use hydrogen peroxide to destroy them. The peroxide is toxic to both the cell and the pathogen and so is kept within a special compartment, called a phagosome. See more Hydrogen peroxide is a chemical compound with the formula H2O2. In its pure form, it is a very pale blue liquid that is slightly more viscous than water. It is used as an oxidizer, bleaching agent, and antiseptic, … See more Today, hydrogen peroxide is manufactured almost exclusively by the anthraquinone process, which was originally developed by See more Decomposition Hydrogen peroxide decomposes to form water and oxygen with a ΔH of –2884.5 kJ/kg and a ΔS of 70.5 J/(mol·K): The rate of … See more Bleaching About 60% of the world's production of hydrogen peroxide is used for pulp- and paper-bleaching.
