In setting up your 3 kinetics experiment, you will be mixing different volumes the two reactants (oxalic acid (H2C2O4) and potassium permanganate (KMnO4)). If you mix 10 ml of 0.02 M with 20 ml of 0.5 M oxalic acid, what is the concentration of H2C2O4 in the mixture? Hint: Use M1V1 = M2 V2.

In this experiment you will use an oxidation - reduction titration to determine the percent of oxalate ion, CO2 in an unknown sample containing oxalate ion. Potassium permanganate (KMnO.) will be titrated against the oxalic acid (C2H:08) as shown by the following oxidation-reduction reaction: +3 +7 5C,044 2MnO4 + 16H* → 10CO, 8H0 + 2Mn2 +4 + + Mno. Mn? is the reduction process C2042 → CO2 is the oxidation process The underlying principle behind a titration is that an...

(III) Oxalate Hydrate Salt
The iron(II) ions from
Fe(NH4)2(SO4)2•6H2O
will be precipitated as iron(II) oxalate.

The supernatant liquid, containing the ammonium and sulfate
ions, as well as excess oxalate ions and oxalic acid will be
decanted and discarded. The solid will then be re-dissolved and the
iron(II) ions will be oxidized to iron(III) ions by reaction with
hydrogen peroxide.
