Question
Please explain the reason
sum_n=3 ^infinity A solution containing AgNO_3 is mixed with a solution of NaCl to form a solution that is 0.10 mol L^-1 in AgNO_3 and 0.075 mol L-1 in NaCl. What will happen once these solutions are mixed? K_sp(AgCl) = 1.77 times10^-10. Nothing will happen since the molar solubility of AgCl is higher than the solution concentrations. Silver chloride will precipitate out of the solution, leaving an unsaturated solution of AgCl. Nothing will happen since NaCl and AgNO_3 are both soluble compounds. Silver chloride will precipitate, leaving a pure solution of NaNO_3. Silver chloride will precipitate out of the solution, leaving a saturated AgCl solution.Explanation / Answer
Ksp = [Ag+][Cl-] = 1.77x10^-10
Q = [Ag+][Cl-] = (0.10)(0.075) = 7.5x10^-3
Ksp < Q
answer is: E) silver chloride will precipitate out of solution, leaving a saturated AgCl solution.
