A solution containing AgNO₃ is mixed with a solution of NaCl to form a solution that is 0.10 mol L^-1 in AgNO₃ and 0.075 mol L^-1 in NaCl. What will happen once these solutions are mixed? K_sp (AgCl) = 1.77 × 10^-10. A) Nothing will happen since the molar solubility of AgCl is higher than the solution concentrations. B) Silver chloride will precipitate out of the solution, leaving an unsaturated solution of AgCl. C) Silver chloride will precipitate out of the solution, leaving a saturated AgCl solution. D) Nothing will happen since NaCl and AgNO₃ are both soluble compounds. E) Silver chloride will precipitate, leaving a pure solution of NaNO₃.

When the two solutions are mixed, the Ag+ and Cl- ions will combine to form solid AgCl. The equilibrium constant for the formation of AgCl (Ksp) is 1.77 × 10-10. The solution concentrations of AgNO3 and NaCl are both higher than the molar solubility of AgCl (1.33 × 10-5 mol L-1), so AgCl will precipitate until the solution becomes saturated with AgCl. Therefore, option C is the correct answer.

A Solution Containing AgNO3 Is Mixed with a Solution of NaCl

A Solution Containing AgNO₃ Is Mixed with a Solution of NaCl
