A Solution Containing AgNO₃ Is Mixed with a Solution of NaCl

question 37

Multiple Choice

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.
