What is the pH of Hydrogen Peroxide?
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...

Why does water dissolve an alka seltzer tablet faster then hydrogen peroxide?
because the Ph is 33 when hydrogen peroxide is 12

What is the pH of 3 percent hydrogen peroxide and water solution?
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.
What experiment shows how pH affects enzymes?
Equipment: - Hydrogen Peroxide - Catalase - Equally sized paper slips (a small rectangle, 2 cm X 1 cm) - Tweezers - Beaker - Stopwatch -pH testing strips -Acids (lemon juice, vinegar, etc.) -Bases (milk, baking soda, ammonia etc.) For the control, take one of the paper slips, using the tweezers, and dip it into the catalase, then place the catalase covered slip at the bottom of a beaker filled about halfway with hydrogen peroxide. You cannot simply drop the slip into the beaker, you must stick the tweezers into the beaker so that they reach the bottom, and then release. When the catalase contacts the hydrogen peroxide the hydrogen peroxide will release oxygen as a reaction, these oxygen bubbles in the liquid will push the paper to the top. Start the stop watch precisely when the strip enters the hydrogen peroxide, to measure the rate of reaction, and stop it again when the slip reaches the top. And finally for the affect of pH on the enzyme, simply change the pH of the hydrogen peroxide adding an acid, or a base. Then, just rerun the experiment and it will be evident that the pH affects the rate of reaction. The pH of hydrogen peroxide is roughly 2, or in that region, so adding a base will speed up the reaction, because the pH optimum of catalase is around 7.
What Metal you wash your dishes in?
Hydrogen Peroxide because this contains the correct 'ph' number that will split the dirt cells and destroy bacteria.
