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, usually as a dilute solution (3%–6% by weight) in water for consumer use, and in higher … See more The boiling point of H2O2 has been extrapolated as being 150.2 °C (302.4 °F), approximately 50 °C (90 °F) higher than water. In practice, hydrogen peroxide will undergo potentially explosive thermal decomposition if … 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 decomposition increases with rise in temperature, concentration, and pH (H2O2 being … See more Bleaching About 60% of the world's production of hydrogen peroxide is used for pulp- and paper-bleaching. … See more Alexander von Humboldt is sometimes said to have been the first to report the first synthetic peroxide, barium peroxide, in 1799 as a by … See more Today, hydrogen peroxide is manufactured almost exclusively by the anthraquinone process, which was originally developed by BASF in 1939. It begins with the … See more Hydrogen peroxide is formed in humans and other animals as a short-lived product in biochemical processes and is toxic to cells. The toxicity is due to oxidation of proteins, membrane lipids and DNA by the peroxide ions. The class of biological enzymes See more Regulations vary, but low concentrations, such as 5%, are widely available and legal to buy for medical use. Most over-the-counter peroxide solutions are not suitable for ingestion. … See more WebThe reaction serves to convert toxic hydrogen peroxide (H2O2), a product of metabolism, into water and oxygen. This reaction occurs spontaneously, but slowly, in the absence of peroxidase. ... determine whether the rate is a function of enzyme concentration. PROCEDURE 1.
