Hydrogen peroxide, H2O2, reacts rapidly with acidified potassium manganate(VII), KMnO4. 5H2O2(aq) + 2MnO4¯(aq) + 6H+(aq) → 502(g) + 8H2O(l) + 2Mn2+(aq) You will determine the concentration of a solution of hydrogen peroxide. You will first dilute the solution and then carry out a titration with acidified potassium manganate(VII). FA 1 is aqueous hydrogen peroxide, H2O2. FA 2 is 0.0300 moldm¯³ potassium manganate(VII), KMnO4. FA 3 is 1.0 moldm¯³ sulfuric acid, H2SO4. (a) Method Dilution of FA 1 • Pipette 25.0 cm³ of FA 1 into the 250 cm³ volumetric flask. • Add distilled water to make 250 cm³ of solution. • Shake the flask thoroughly. • Label this diluted solution of hydrogen peroxide FA 4. Titration • Fill the burette with FA 2. • Rinse the 25.0 cm³ pipette with distilled water and then with FA 4. • Pipette 25.0 cm³ of FA 4 into a conical flask. • Use the 25 cm³ measuring cylinder to add 10cm³ of FA 3 to the conical flask. • Perform a rough titration and record your burette readings in the space below. The rough titre is = ______________ cm³. • Carry out as many accurate titrations as you think necessary to obtain consistent results. • Make sure your recorded results show the precision of your practical work. • Record, in a suitable form in the space for results, all your burette readings and the volume of FA 2 added in each accurate titration. Keep FA 1 for use in Questions 2 and 3. Keep FA 2 for use in Question 3.
