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 concentrations … 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 … See more Hydrogen peroxide is formed in humans and other animals as a short-lived product in biochemical processes and is toxic to cells. … See more Regulations vary, but low concentrations, such as 5%, are widely available and legal to buy for medical use.
