## What does volume of hydrogen peroxide mean?

Volume is the amount of oxygen that is contained in a given amount of peroxide. For example, 3% hydrogen peroxide is V10 or 10 volume, because it will release 10 times it’s volume in oxygen. One pint of 3% hydrogen peroxide will release 10 pints of oxygen as it breaks down.2020-04-04

## What does a 20 volume hydrogen peroxide refer?

20 volume of H2O2 is equivalent to 6.07% w/v or 1.786 mol/L of H2O2. These equivalences are obtained knowing that 20 volume means that 1 L of H2O2 solution produces 20 L of oxygen by decomposition under normal conditions, that is, assuming 1 mol of O2 at 1 atm and 0 °C.
