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...
Pure hydrogen peroxide has a pH of 6.2
level6
between 2,5 and 4,5
Hydrogen is an element.Hydrogen peroxide is a compound.

Pure hydrogen peroxide has a pH of 6.2
level6
pH 4.4 :)
because the Ph is 33 when hydrogen peroxide is 12
scale pH <--- HUH? hehe
between 2,5 and 4,5
Answering "Experiment on the effect of the PH of enzymatic reaction using hydrogen peroxide and extract of spinach leaf?"
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 is an element.Hydrogen peroxide is a compound.
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.
