Twenty Volume Peroxide Question
    #3619887 - 01/12/05 08:30 PM (12 years, 4 months ago)

A FOAF has is being given some "Twenty Volume' Peroxide tomorrow. It is lab grade.

Anyhow, to get to a 3% concentration my FOAF has been told mix 3ml peroxide to 97ml distilled water, but wasn't totally sure this was the case.

Is it? If so, is this the strongest peroxide available?

dude just goto the store and buy a bottle of it in the first aid section. thats always 3% H2O2, keep the concentrated shit sealed well in a cool dark place for posible future uses, not sure what, but hey, a big bottle at the store isnt going to cost much more than a buck.

From Wickipedea;

"In common usage, peroxide is an aqueous solution of hydrogen peroxide (HOOH or H2O2) sold for use as a disinfectant or mild bleach. The usual peroxide of commerce is a dilute solution containing traces of stabilisers, and is sold in either brown glass or opaque polyethylene bottles to minimise the rate of decomposition. The concentrations sold are generally either 3% w/v or 6% w/v; these are sometimes described as "10 volume" and "20 volume", respectively. This refers to the relative volume of oxygen gas produced, at STP, from the complete decomposition of the peroxide. 20 volume peroxide is strong enough to bleach skin it touches, causing unnaturally white blotches."

So the stuff you have is twice as strong as most folks here buy at the grocery store. Use one part of it with 19 parts water for the generally accepted concentration.
