Question
A solution contains 6.56x10^-3 M silver acetate and 1.28x10^-2 M lead nitrate solid ammonium iodide is added slowly to this mixture

ammonium iodide is NH4I

iodide ions will form

Ag+ + I- = AgI

Pb+2 + I- = PbI2

Get Ksp data:

AgI 8.52×10–17; PbI2 9.8×10–9

Therefore, Ksp << Ag than PbI2

then, most likely AgI precipitates first

b)

find [I-] when it begins to precipitate

Ksp = [Ag+][I-]

8.52*10^-17 = (6.56*10^-3)[I-]

[I-] = (8.52*10^-17) / (6.56*10^-3) = 1.2987*10^-14 M
