Chemical equation used: 2 MnO4 + 5 H2O2 + 6 H* 2 Mn2+ + 5 O2 + 8 H2O [MnO4] = 0.0090 M Volume H2O2 used: 1.0 mL Volume H2SO4 used: 7.0 mL Trial 1: 41.9 mL MnO4 used Trial 2: 40.4 mL used Trial 3: 40.01 mL used Remember you want to find the M (mol/L) of H2O2. You must use stoichiometry to find moles of H2O2 and the volume of hydrogen peroxide used to get liters. Calculate the concentration for each trial and average the results.

Chemical equation used:
2 Mn04 + 5 H2O2 + 6 H* →2 Mn2+ + 5 02 + 8 H2O
[MnO4] = 0.0090 M
Volume H2O2 used: 1.0 mL
Volume H2S04 used: 7.0 mL
Trial 1: 41.9 mL MnO4 used
Trial 2: 40.4 mL used
Trial 3: 40.01 mL used
Remember you want to find the M (mol/L) of H2O2. You must use stoichiometry to find
moles of H2O2 and the volume of hydrogen peroxide used to get liters. Calculate the
concentration for each trial and average the results.
