Since NaCl is a strong electrolyte therefore the entire conc. of Cl ions comes from NaCl Ksp AgCl = [Ag+] [Cl]. If solubility of Ag+ = s in NaCl then

(A)

 

NaCl dissociates fully to give [Cl-] = 0.2 and contribution of [Cl-] from AgCl is negligible compared to it.

So, Ksp = [Ag+][Cl-] = 1.8*10^(-10)

 

Find [Ag+] which will be the solubility.
