The concentration of SO32- in a solution is determined by titration with a 0.1355 M permanganate solution. The balanced net ionic equation for the reaction is: 2MnO4-(aq) + 5SO32-(aq) + 6H3O+(aq) 2Mn2+(aq) + 5SO42-(aq) + 9H2O(l) (a) If 23.89 mL of the 0.1355 M permanganate solution are needed to react completely with 25.00 mL of the SO32- solution, what is the concentration of the SO32- solution? M (b) Which of the two solutions was in the buret during the titration? (c) Suppose at the end of the titration, the solution containing the Mn2+ ion is transferred to a volumetric flask and diluted to 400. mL. What is the concentration of Mn2+ in the diluted solution? M
