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∘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 (Ksp) of AgCl and AgI at the temperature of the experiment? (In both cases normal calomel electrode is cathode).
(a) 103
(b) 106
(c) 10−3
(d) 10−6
