akcapr Posted March 23, 2005 Share Posted March 23, 2005 I recently (literally 25 min ago) made some Hydrogen peroxide form 3% solution. Ithink its about 30%, but i want to know for sure. how could i tst this new solutions concentraton. thxx for da help Link to comment Share on other sites More sharing options...
oncetoomany Posted March 23, 2005 Share Posted March 23, 2005 expose to catalyse solution then compare before and after weights. Link to comment Share on other sites More sharing options...
Crash Posted March 23, 2005 Share Posted March 23, 2005 You could measure the reaction rates against a known standard but this would have to be very tightly done for temp etc.etc. how did you purify it? using freezing techniques to isolate it out?

BenSon Posted March 23, 2005 Share Posted March 23, 2005 If you recorded the volumes then use this equation C1V1=C2V2 This means that the concentration times the volume of the original solution is equal to the concentration times the volume of the second solution. So you know the concentration of the first solution (3%) and you should know how much you started with. And you can measure how much you have now, with those three values you can find the exact concentration of the final solution which will be 30% if your correct. ~Scott Link to comment Share on other sites More sharing options...
YT2095 Posted March 23, 2005 Share Posted March 23, 2005 H2O2 is often measured in Vols as well as percentage. the Vols unit is how many times more Oxygen can be liberated compared to the liquid volume. for instance, If I have 1 litre of H2O2 liquid, and react this (choose your catalyst) to form oxygen, and I get 2 litres of Oxygen, then my starting liquid was 2 Vols a 9 Vols liquid (30%) will give off 9x it`s liquid volume as Oxygen gas. (measured at SRTP) hope that helps Link to comment Share on other sites More sharing options...
