Want this question answered?
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.
(x L)((12%) = (100 L)(2%)x = 16.7 liters
I am a hairstylist and have never heard of peroxide 6 percent. Normally peroxides come in 10vol 20vol 30vol and 40vol. If you are going darker or trying to cover greys you use a 10vol. If you are trying to achieve a lighter look you would use the other three volumes 20-30-40. The difference between them is how long you want your hair to process and what level of lightness you want to achieve. The higher the volume (30-40vol) processes your hair faster and can get it lighter. I would recommend using a 20 volume to start if you want to lighten. It is a safe way to start out. 6% peroxide is also known as 20 volume developer as 3% is 10 volume, 9% is 30 volume, and 12% is 40 volume. Also......for gray coverage...always use 20 volume. 10 volume will NOT cover gray hair.
84%
x+y = 240 0.06x + 0.12y =240(0.07) = 16.8 0.06x + 0.12(240 - x) = 16.8 0.06x + 28.8 - 0.12x = 16.8 -0.06x = -12 x = 200.......6% solution y = 40........12% solution
no.
dilute twice in volume
Possibly, by low pressure distillation, but it is not easy.
The difference between 6%, 9%, and 12% Hydrogen Peroxide solution is the Hydrogen content.
pH 4.4 :)
Amazon sells Hydrogen Peroxide 12% in 16 Ounces for $13.83.......I have not seen a 10% yet..

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
9/12 = 0.75 = 75%
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 is 15% of 80.
because the Ph is 33 when hydrogen peroxide is 12
