Phase Changes of Hydrogen Peroxide
October 2005
At room temperature Hydrogen Peroxide is a pale blue liquid
When it
that looks almost clear and that has syrup like consistence. freezes the color is about the same as when it is a liquid. The
chemical formula for Hydrogen Peroxide is H2O2.lt is a substance
.
that is a combination of Hydrogen and Oxygen. Hydrogen Peroxide
has a 50 degree C wider range of temperature at its liquid state than water does; it boils at 150.2C and freezes at -0.43c. Unlike water which
boils at 100C and freezes at OC. The kind of Hydrogen Peroxide that you buy at the store is usually 3%; it freezes at 0C and most
likely has a similar boiling point to water as well.
