Question

The permanganate ion (MnO4- ) is often used in redox titrations. The strongly colored (violet)
the permanganate ion forms the slightly pink Mn2+ ion upon reaction in acidic solution.
Permanganate solutions are prepared by dissolving solid potassium permanganate. At
preparation and storage of the solution, however, often forms brownstone (MnO 2 (s)) which must
filtered before use. The concentration of the solution is therefore determined directly before
use by titration in sulfuric acid solution against sodium oxalate (Na2 C2 O4 ;
easily soluble salt that serves as the primary standard) whereby the oxalic acid forms carbon dioxide (gas).
Calculate the concentration of a potassium permanganate solution from the following data.
0.6501 gram of sodium oxalate is weighed and consumes 20.00 mL of the prepared
the potassium permanganate solution.
