Problem

Pure water is saturated with pure solid AgCl, a silver rod is placed in the solution and the potential is measured against normal calomel electrode at 25∘C25^\circ\text{C}. This experiment is then repeated with a saturated solution of AgI. If the difference in potential in the two cases is 0.177 V, what is the ratio of solubility product (KspK_{sp}) of AgCl and AgI at the temperature of the experiment? (In both cases normal calomel electrode is cathode). (a) 10310^3 (b) 10610^6 (c) 10−310^{-3} (d) 10−610^{-6}
