A solution of potassium permaganate is standardized with iron metal, a primary standard. The iron is dissolved in acid, reduced to Fe(II), and titrated with permanganate.
5Fe^2+(aq)+MnO4^-(aq)+ 8H+(aq)----> 5 Fe^3+(aq) + Mn^2+ +4H2O (l)
33.17 ml of permanganate is required to titrate a 0.5497-g sample of iron. Calculate the molariity of the potassium permanganate solution.
