Silver chloride, AgCl, is a sparingly soluble solid. Answer the following questions about a saturated solution prepared by placing solid silver chloride in a 3.49 10-5 M NaCl(aq) solution. At some temperature, the silver ion concentration, [Ag+], was found to be 4.10 10-6 M. (a) What is the concentration of chloride ions, [Cl ? ], in the resulting solution? M (b) What is the molar solubility of silver chloride, AgCl, in 3.49 10-5 M NaCl? M (c) The solubility of AgCl(s) in pure water is 1.26 10-5 M. Did the solubility increase or decrease in 3.49 10-5 M NaCl solution? (d) What is the solubility product constant, Ksp, for silver chloride, AgCl? Ksp =
