Even though AgCl (,K, sp = 1.6 × 10 –10), AgBr (,K, sp = 5.0 × 10 –13), and AgI (,K, sp = 1.5 × 10 –16) are each quite insoluble, we cannot prepare a homogeneous solid mixture of them by adding Ag + to a solution of Cl –, Br –, and I –; essentially all of the AgI will precipitate before any of the other solid halides form because of its smaller value for ,K, sp.
