pH 4.4
:)
no.
because the Ph is 33 when hydrogen peroxide is 12
dilute twice in volume
Possibly, by low pressure distillation, but it is not easy.
9/100 = 12 / (100 +x) so 0.09 (100+x) = 12 so 9 +0.09x =12 therefore 0.09x = 12-9 and thus x = 3/0.09 = 33.334 So to 100g of 12% peroxide would need to add 33.34 g water. To put another way to every 3 parts peroxide add 1 part water. Ratio of 3:1 peroxide:water
Amazon sells Hydrogen Peroxide 12% in 16 Ounces for $13.83.......I have not seen a 10% yet..
The difference between 6%, 9%, and 12% Hydrogen Peroxide solution is the Hydrogen content.
it will become 9 percent hydrogen peroxide and it should be okay to dye your hair with. it might look orangish at first but will turn blond like eminem. it might be really strong do not get that in your eyes.
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.

12 *.10 = 1.2
10 percent = 60/10 = 6 10 percent + 10 percent = 6 + 6 = 12 20% of $60 is $12
10 percent of 12 ounces is 1.2 ounces.
120 percent of 10 is 12.
