Question 1: Hydrogen peroxide can be purchased in drug stores for use as anantiseptic. A sample of such a solution weighing 10.0 g was acidified with sulfuricacid and titrated with a 0.200 M KMNO4 solution. The peroxide was oxidized tooxygen gas. The titration required 17.6 mL of the permanganate solution.2 KMNO4 + 3 H2SO4 + 5 H2O2- 2 MNSO4 + K2SO4 + 5 O2 + 8 H20Question 1-2: b.
