I'll have to admit this one had me stumped for awhile..with not being familar with the "volume" nomenclature for peroxide. So, I did some research on it (finding little) and finally relied on my favorite wikipedia.com. It provided me with the decomposition equation for Hydrogen peroxide to water and oxygen...

2H2O2 ----> 2H2O + O2

Volume peroxide refers to the "volume" of oxygen gas produced from the decomposition of 1 volume of the solution.

That is: if 1 liter of a peroxide solution produces 10 volumes of O2, then it is labeled 10 volume. If 1 volume solution yeilds 20 volumes O2 = 20 volume. You get the picture...

What percentage is that?

Quick table:

10 vol = 3% H2O2
20 vol = 6% H2O2
30 vol = 9% H2O2
40 vol = 12% H2O2

If you want to convert volume to %

(Volume value) x 0.3 = percent

or

To convert % to volume

(% value) divided by 0.3 = volume.

These are rough calculations but will get you in the ball park (+/ - a couple of percent)...

Hope this helps someone...

See if Ken can make that sticky at the top. Goes along nicely with the other peroxide post.

I always wondered why peroxide sold at beauty supply stores was labeled by volume, and not percentage. I'm certain that all beauticians are fully aware of the scientific meaning of "volume" when using peroxide...LOL!

I'll just bump it every 12 years or so..

You probably need to bump it every 2 weeks, instead of every 2 years!
