Pure hydrogen peroxide has a pH of 6.2
between 2,5 and 4,5
YVA_ANG left this answer to a previous same question in Yahoo answers: The pH of hydrogen peroxide at: 35% = 2.5 50% = 1.8 70% = 0.5 Hopefully this helps http://chemicalland21.com/industrialchem...
Hydrogen peroxide react with chlorine.The reaction is the following:H2O2 + Cl2 = 2 HCl + O2
Hydrogen is an element.Hydrogen peroxide is a compound.

pH 4.4 :)
because the Ph is 33 when hydrogen peroxide is 12
scale pH <--- HUH? hehe
between 2,5 and 4,5

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.

Hydrogen peroxide is a teeth whitener, google "hydrogen peroxide teeth."

Hydrogen peroxide decomposes through a thermodynamically favourable reaction: 2H2O2 → 2H2O + O2 The rate of this reaction increases with temperature and depends on factors like its concentration, pH and the prescence of a catalyst. Thus, a bottle of hydrogen peroxide can decompose when stored under unfavourable conditions.
