Potassium permanganate in acidic solution is used to titrate a solution of iron(II) ions, with which it reacts according to MnO4 (aq) + 5Fe²*(aq)+8H3O*(aq)–Mn²*(aq) + 5Fe³*(aq)+12H2O(1) A potassium permanganate solution is prepared by dissolving 16.89 g of KMNO4 in water and diluting to a total volume of 1.000 L. A total of 15.80 mL of this solution is required to reach the endpoint in a titration of a 150.0-mL sample containing Fe2*(aq). Determine the concentration of Fe2* in the priginal solution.

Potassium permanganate in acidic solution is used to titrate a solution of iron(II) ions, with which it reacts according to
MnO, (aq) + 5Fe²*(aq)+8H3O*(aq)-
→Mn²+
(aq) + 5Fe*(aq)+12H20(1)
A potassium permanganate solution is prepared by dissolving 16.89 g of KMNO4 in water and diluting to a total volume of 1.000 L. A total of 15.80 mL
of this solution is required to reach the endpoint in a titration of a 150.0-mL sample containing Fe2*(aq). Determine the concentration of Fe2+ in the
original solution.
