The Ksp of AgCl at 25 oC is 1.6 x 10-10. Consider a solution that is 1.0 x 10-4 M CaCl2 and 1.0 x 10-6 M AgNO3. 1. Q < Ksp and a precipitate will not form. 2. Q < Ksp and a precipitate will form. 3. The solution is saturated. 4. Q > Ksp and a precipitate will not form. 5. Q > Ksp and a precipitate will form.
