Question:

What mass of solid potassium oxalate (K{eq}_2 {/eq}C{eq}_2 {/eq}O{eq}_4 {/eq}), when dissolved in an acidic solution, would be titrated by exactly 40.0 mL of 0.0423 M potassium permanganate (KMnO{eq}_4 {/eq}) solution?

(Mn{eq}^{2+} {/eq} ions and carbon dioxide are produced in the reaction.)

Redox Titration:

Redox titration is one of the kinds of titration in which the reaction that is used for quantification is a redox reaction. Usually, the titrant used is a strong oxidizing agent to promote a complete redox reaction between the two species, titrant and analyte.

The balanced redox reaction between oxalic acid and potassium permanganate is:

{eq}\rm 2KMnO_4 + 16H^+ + 5 K_2C_2O_4 \to 12K^+ + 2Mn^{2+} + 8H_2O +...
