The solubility product of silver chloride at 25 °C is \(K_{sp}=1.8\times10^{-10}\). A solution is prepared by dissolving \(0.010\ \text{mol}\) of NaCl in \(1.0\ \text{L}\) of water, after which excess solid AgCl is added until equilibrium is reached. (a) Calculate the equilibrium concentration of \(\mathrm{Ag^+}\) ions in the solution. (b) If the solution is then diluted to a total volume of \(2.0\ \text{L}\) without adding or removing any solid, what is the new concentration of \(\mathrm{Ag^+}\) ions?

Answer Options

A. a) \(1.8\times10^{-7}\ \text{M}\); b) \(9.0\times10^{-8}\ \text{M}\)
B. a) \(9.0\times10^{-9}\ \text{M}\); b) \(4.5\times10^{-9}\ \text{M}\)
Correct Answer C. a) \(1.8\times10^{-8}\ \text{M}\); b) \(9.0\times10^{-9}\ \text{M}\)
D. a) \(3.6\times10^{-8}\ \text{M}\); b) \(1.8\times10^{-8}\ \text{M}\)
Correct Answer
C
Correct Option:
a) \(1.8\times10^{-8}\ \text{M}\); b) \(9.0\times10^{-9}\ \text{M}\)
