Question

The concentration of hydrogen peroxide solution can be found by a redox titration with acidified potassium permanganate solution. It was found that 17mL of the potassium permanganate solution reacted with 23mL of 0.03M hydrogen peroxide solution when titrated. Calculate the concentration of the potassium permanganate solution. 2 MnO4-(aq) + 6 H+(aq) + 5 H2O2(aq) ? 2 Mn2+(aq) + 4 H2O(l) + 5 O2(aq) 0.1015 0.0171 0.1067 0.0767 0.0123 0.0162 other

Step 1

Given: Volume of H2O2 solution = 0.023 L Concentration of H2O2 solution = 0.03 M Number of moles of H2O2 = concentration x volume Number of moles of H2O2 = 0.03 mol/L x 0.023 L Number of moles of H2O2 = 0.00069 mol Show more…
