Results and Discussion Potassium permanganate‚ KMnO4‚ is widely used as an oxidizing agent in volumetric analysis. In acid solution‚ MnO4- ion undergoes reduction to Mn2+ ion as shown in the equation: 8 H+(aq) + MnO4-(aq) + 5e- → Mn2+(aq) + 4 H2O(l). Since the MnO4- ion is violet and the Mn2+ ion is nearly colorless‚ the end point in titrations using MnO4- as the titrant can be taken as the first permanent pink color that appears in the solution being titrated.1 The number of moles of potassium
