Question:

Suppose that 25.0 mL of a solution of Ag+ ions of unknown concentration is titrated with 0.015 m KI(aq) at 25°C. A silver electrode is immersed in this solution, and its potential is measured relative to a standard hydrogen electrode. A total of 16.7 mL of KI(aq) was required to reach the stoichiometric point, when the potential was 0.325 V.

(a) What is the molar concentration of Ag+ in the solution?

(b) Evaluate Ksp for AgI from these data.
