1. Solubility in Water:
AgCl $\rightleftharpoons$ Ag$^+$ + Cl$^-$ $K_{sp} = [Ag^+][Cl^-] = s^2$ where s is the solubility in mol/L.
Given $K_{sp} = 10^{-10}$ $s = \sqrt{10^{-10}} = 10^{-5}$ mol/L
2. Solubility in 0.1 M KCl Solution: In 0.1 M KCl solution, [Cl$^-$] = 0.1 M (due to common ion effect).
$K_{sp} = [Ag^+][Cl^-] = s'(0.1) = 10^{-10}$ where s' is solubility in 0.1 M KCl. $s' = \frac{10^{-10}}{0.1} = 10^{-9}$ mol/L
3. Calculate the Ratio:
Ratio $= \frac{Solubility in 0.1 M KCl}{Solubility in water} = \frac{10^{-9}}{10^{-5}} = 10^{-4}$
