Use the reaction quotient to predict whether a precipitate will form. If 12.0 mL of 2.01x10^-4 M CaI_2 are added to 22.0 mL of 9.40x10^-5 M K_2 SO_4 will solid CaSO_4 (Ksp =2.4 x 10-5) precipitate? ____ If a precipitate will not form, what sulfate ion concentration will cause a precipitate of calcium sulfate to form? If a precipitate will form, what is the minimum [SO_4^2-] that could have been present without initiating precipitation? Assume the total volume used in the above example
