    Hydrogen peroxide breaks down into oxygen and water. As a small amount of hydrogen peroxide generates a large volume of oxygen, the oxygen quickly pushes out of the container. [6] The soapy water traps the oxygen, creating bubbles, and turns into foam. [6] About 5-10 drops of food coloring could also be added before the catalyst to dramatize ...

  3. Chemical decomposition - Wikipedia

    en.wikipedia.org/wiki/Chemical_decomposition

    An example of a spontaneous (without addition of an external energy source) decomposition is that of hydrogen peroxide which slowly decomposes into water and oxygen (see video at right): 2 H 2 O 2 → 2 H 2 O + O 2. This reaction is one of the exceptions to the endothermic nature of decomposition reactions.

  4. Hydrogen peroxide - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_peroxide

    Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] 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 for industrial use.

  5. Self accelerating decomposition temperature - Wikipedia

    en.wikipedia.org/wiki/Self_Accelerating...

    A self-accelerating decomposition occurs when the rate of peroxide decomposition is sufficient to generate heat at a faster rate than it can be dissipated to the environment. Temperature is the main factor in determining the decomposition rate, although the size of the package is also important since its dimensions will determine the ability to ...

  7. Hydroperoxide - Wikipedia

    en.wikipedia.org/wiki/Hydroperoxide

    Many industrial peroxides are produced using hydrogen peroxide. Reactions with aldehydes and ketones yield a series of compounds depending on conditions. Specific reactions include addition of hydrogen peroxide across the C=O double bond: R 2 C=O + H 2 O 2 → R 2 C(OH)OOH. In some cases, these hydroperoxides convert to give cyclic diperoxides:

  8. Radiolysis - Wikipedia

    en.wikipedia.org/wiki/Radiolysis

    Radiolysis is the dissociation of molecules by ionizing radiation.It is the cleavage of one or several chemical bonds resulting from exposure to high-energy flux.The radiation in this context is associated with ionizing radiation; radiolysis is therefore distinguished from, for example, photolysis of the Cl 2 molecule into two Cl-radicals, where (ultraviolet or visible spectrum) light is used.

  9. Piranha solution - Wikipedia

    en.wikipedia.org/wiki/Piranha_solution

    Many different mixture ratios are commonly used, and all are called piranha.A typical mixture is 3 parts of concentrated sulfuric acid and 1 part of 30 wt. % hydrogen peroxide solution; [1] other protocols may use a 4:1 or even 7:1 mixture.
