The known metal ion solution used in this experiment contains 0.10 M of each of the six metal ions. What are the initial concentrations of Ag, Pb, and Cl before any precipitation/reaction occurs, but after the mixing (i.e. dilution) of equal volumes of 3 M HCl and the known solution?
What is the [Ag]? Express your answer to two significant figures.
Assume all the present Pb2+ and Ag+ precipitate out of solution. Use the remaining Cl- concentration and the Ksp and Kf reactions for AgCl and AgCl2-, respectively, to determine how much Ag+ remains in solution (in M)? Express your answer to two significant figures. The Ksp for AgCl = 1.8 x 10-10 and the Kf for AgCl2- = 1.8 x 105.
