Ph level of hydrogen peroxide
Webb17 maj 2024 · Redox reactions: Depending on the pH level, hydrogen peroxide has powerful reducing and oxidising (redox) properties. As an oxidising agent, it can remove electrons from other substances. As a reducing agent, it can reduce various inorganic ions. 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 heated to this temperature. It may be safely distilled at lower temperatures under reduced pressure. Hydrogen peroxide (H2O2) is a nonplanar molecule with (twisted) C2 symmetry; this was first sh…
