Since the dissociation constant for hydrogen peroxide is 2.4 x 10^-12 (very very small) if only a 3% concentration were to be mixed with water the pH would be negligible. However the main reason Hydrogen peroxide stings when you spill or pour it on a cut to disinfect it is because of its fairly high reactivity.

Does peroxide have ammonia?

No. Peroxide is a solution of hydrogen peroxide (H2O2) in water. Ammonia (NH3) is completely different.

What would happen if platinum was added to hydrogen peroxide solution?

The platinum acts as catalyst and causes the hydrogen peroxide to decompose into water and oxygen.

Is hydrogen peroxide a compound or elements or mixture?

H2O2 is a covalent compound, as a pure sample of it cannot be split into other separate compounds by physical means. However, the bottle labeled "Hydrogen Peroxide" in your medicine cabinet is actually a mixture (it's about a 3% solution of hydrogen peroxide the compound in water). I hope i could help out :)

How do you dilute 20 volume hydrogen peroxide to make a 3 percent solution?

20 volume is 6% solution. To make it 3% solution just add same volume of water to the original 6% solution and you have double volume of 3% solution.

How fast does hydrogen peroxide solution break down?

This depends on a variety of factors such as temperature, the strength of the hydrogen peroxide solution and the presence or not of a catalyst, like manganese dioxide or silver. Acidic solutions also exhibit better stability. So, a slightly acidic and weak solution of hydrogen peroxide, stored in a cool place, will break down the slowest. Hydrogen peroxide decomposes to form water and oxygen, liberating heat in the process.
