A 1.00 L aqueous solution is prepared by adding excess solid AgCl to pure water at 25 °C. The solubility product of AgCl at this temperature is \(K_{sp}=1.8\times10^{-10}\). (a) Calculate the molar solubility of AgCl in pure water. (b) The solution is then mixed with 0.10 mol L\(^{-1}\) NaCl. Determine the new molar solubility of AgCl in the presence of the common ion. (c) If 0.500 g of solid AgCl is added to the NaCl‑containing solution, how much AgCl remains dissolved (in grams) at equilibrium? Give your answer to three significant figures.
