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

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...
