Question

Potassium permanganate in acidic solution is used to titrate a solution of copper(I) ions, with which it reacts according to

MnO₄^-(aq) + 5Cu⁺(aq)+8H₃O⁺(aq)Mn²⁺(aq) + 5Cu²⁺(aq)+12H₂O(l)

A potassium permanganate solution is prepared by dissolving 23.14 g of KMnO₄ in water and diluting to a total volume of 1.000 L. A total of 15.61 mL of this solution is required to reach the endpoint in a titration of a 200.0-mL sample containing Cu⁺(aq). Determine the concentration of Cu⁺ in the original solution.
