Hydrogen peroxide

Hydrogen peroxide solution is colorless transparent liquid. Pure hydrogen peroxide is a light blue viscous liquid and can be dissolved in water and alcohol, the melting point is 0.43 °C, and boiling point is 150.2 °C. The density is 1.71g/cm3 when solidified, and it decreases with increasing temperature. Because of stronger association than H2O, the hydrogen peroxide has higher dielectric constant and boiling point. The pure hydrogen peroxide is very stable, but if heated to 153 ℃, it will be vigorously decomposed into water and oxygen.
