Evaporation of h202 in a h20 solution

  1. Feb 18, 2013 #1
    I need to make a gas consisting of 1 % h202. Would pouring a liquid consisting of 1% h202 and 99% h20 into a pitre dish ,and using a small fan directed at the surface result in a gaseous solution of 1% h202. The answer seems simple to me, but I have no background ,and am usually wrong in these matters.

    In general, H2O2 and H2O can evaporate at different rates (well, they will do, the question is just how different the rates are). If you evaporate everything, it should be fine, however.

    Think about it - if the vapors above the liquid had the same composition the liquid has, you won't be able to drink anything stronger than wine.
