Question

If 12.0 mL of 7.88×10^-4 M AgCH₃COO are added to 12.0 mL of 8.00×10^-5 M NH₄Cl, will solid AgCl (K_sp = 1.8×10^-10) precipitate?  _____(yes or no)

If a precipitate will not form, what chloride ion concentration will cause a precipitate of silver chloride to form? If a precipitate will form, what is the minimum [Cl^-] that could have been present without initiating precipitation? Assume the total volume used in the above example.
