Freezing temperature of hydrogen peroxide
Webhydrogen peroxide, until the chamber was inverted at time 0. O 2 quantities produced were measured for 60 seconds at 5 second intervals. Variable 1, Temperature One paper strip of enzyme and 20 mL of 1.5% H 2O 2 at pH 7 were used for each trial. The temperature of the reaction was changed for each trial by changing the temperature of the water in 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…
