You don't calculate concentration of H2
in the titrated solution. Instead, you calculate number of moles of H2
titrated, and as you know volume of aliquot of hydrogen peroxide taken, you can calculate concentration in the ORIGINAL sample. So yes, dilution of your aliquot doesn't matter, as it doesn't change number of moles of H2
Also, how much sulfuric acid would be enough to acidify H2O2?
Recipe from my book: put solution containing 40-70 mg H2
into 500 mL flask. Dilute to 200 mL, add 20 mL 30% H2
, titrate with 0.1n permanganate.
