question 20

Short Answer

A permanganate solution is prepared by dissolving 20.0123 g KMnO₄ in 500 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? ⇋
