A permanganate solution is standardized by titrating it with a 0.1491 M hydrogen peroxide solution. The balanced net ionic equation for the reaction is: 2MnO4-(aq) + 5H2O2(aq)+6H3O+(aq)2Mn2+(aq) + 5O2(g)+14H2O(l) If 21.22 mL of the 0.1491 M hydrogen peroxide solution is required to react completely with 25.00 mL of the permanganate solution, calculate the concentration of the permanganate solution.
