KI(aq) is slowly added to a solution with [Pb^2+]= [Ag^+]=0.10 M . For PbI_2, K_sp=7.1 ×10^-9 ; for AgI K_sp=8.5 ×10^-17 (a) Which precipitate should form first, PbI_2 or AgI? (b) What [I^-] is required for the second cation to begin to precipitate? (c) What concentration of the first cation to precipitate remains in solution at the point at which the second cation begins to precipitate? (d) Can Pb^2+(aq) and Ag^+(aq) be effectively sepa- rated by fractional precipitation of their iodides?
