The concentration of MnO4– in an acidic solution can be determined by titration with As2O3. A 0.1762 g of As2O3 was dissolved in a dilute acidic solution then the resulting solution was titrated with a KMnO4 solution. A total of 28.5 mL of the KMnO4 solution was used to reach the endpoint. Calculate the concentration of the KMnO4 solution.
MnO4– → Mn2+
As2O3 → H3AsO4
