REPORT SHEET: How much hydrogen peroxide is in commercial hydrogenperoxide?Date of the experiment: Student Name:(This is a word document – fill in your answers and add space as needed)Prelab Questions: 1.You have used a graduated cylinder to measure stock MnO4-solution and a plastic bottle to prepare a working solution of MnO4-that you will later use to determine the amount of hydrogen peroxide. Justify the use of a graduated cylinder and a plastic bottle for preparing MnO4- 2.Define primary standard, endpoint and equivalence point.3.In the experiment 25 mL of 3 M H2SO4is used. Will that volume be measured with a 25.00 mL pipet or a graduated cylinder?4.A 25.00 mL H2O2solution required 22.50 mL of 0.01881 M MnO4-for titration to the end-point. Given that the original H2O2was diluted 1 in 20 before titration withthe MnO4-, (i) what is the molarity of the diluted H2O2? (ii) What is the molarity of the original H2O2solution? (iii) What is the % w/w of H2O2in the original solution, .
