1. The problem statement, all variables and given/known data You are provided with a solution of hydrogen peroxide which is known to be approximately ‘100-volume’. Plan two experiments that would enable you to determine the exact concentration of H2O2 in mol dm-3, in this solution. One of your experiments should involve a redox titration with potassium manganate (VII). The other experiment should not involve a titration. 2. Relevant equations 2KMnO4 (aq) + 5H2O2 (aq) + 3H2SO4 (aq) --> 2MnSO4 (aq) + K2SO4 (aq) +5O2 (g) + 8H2O (l). 2H2O2 --> 2H2O + O2 3. My questions Why is KMnO4 it's own indicator? What is meant by 100-Volume and how can i put it into context? What catalyses the disproportionation of h2o2? 4. The attempt at a solution The end point of this reaction is noted by a pale pink colour. No indicator is required as the solution goes pale pink once all of the H2O2 has reacted. I know this has something to do with the redox chemistry but im not exactly sure. 100-Volume one i believe this means one volume of h2o2 realeses 100 volumes of oxygen when catalytically decomposed. what does it mean by volume? And how can i use this to determine conc of h2o2 as the second experiment. Liver?
