A permanganate solution is prepared by dissolving 20.0123 g KMnO4 in 588 mL of distilled water and boiled for 1 hour to remove any organic material. Following sintered-glass filtration, the solution is quantitatively transferred to a 1.0 L volumetric flask and diluted to volume with distilled water. The permanganate solution was titrated against 0.1023 M oxalic acid prepared in sulfuric acid solution. A 50.00 mL aliquot of oxalic acid solution required 16.68 ml of permanganate solution. A titration blank required 0.04 mL of permanganate. What is the permanganate molarity? 5 H₂C₂O4(aq) +2 MnO4 (aq) + 6H*(aq) 10 CO₂(g) _ 2 Mn2+ (aq)+ 8 H₂0 (1)
