Use the reaction quotient to predict whether a precipitate will form. If 18.0 mL of 7.46x104 M CaCl2 are added to 15.0 mL of 1.30x10M (NH4)2S, will solid CaS (Ksp = 8.0x10 precipitate? no If a precipitate will not form, what sulfide ion concentration will cause a precipitate of calcium sulfide to form? If a precipitate will form, what is the minimum [S2] that could have been present without initiating precipitation? Assume the total volume used in the above example.
