Problem 122

A 0.0251-L sample of a solution of \(\mathrm{Cu}^{+}\) requires 0.0322 L of 0.129M \(\mathrm{KMnO}_{4}\) solution to reach the equivalence point. The products of the reaction are \(\mathrm{Cu}^{2+}\) and \(\mathrm{Mn}^{2+}\). What is the concentration of the \(\mathrm{Cu}^{2+}\) solution?
