Quizplus · Accepted Answer

The solubility product constant for AgCl (KS) is given as 1.57x10^-10. 
AgCl(s) ⇌ Ag+(aq) + Cl-(aq)
At saturation, [Ag+] = [Cl-] since AgCl(s) is a strong electrolyte and disassociates completely. 
So, [Ag+]^2 = KS
[Ag+]^2 = 1.57x10^-10
[Ag+] = sqrt(1.57x10^-10)
[Ag+] = 1.25x10^-5 M
Therefore, the concentration of the silver ion in a saturated solution of silver chloride is 1.25x10^-5 M, which corresponds to choice B.
