Help! A soultion contains 0.100 Pb(NO3) and 1.00x10^-5 M AgNO_3. It is intended to separate out the silver by selective precipitaion of AgI. What is the maximum percentage of total silver that can be recovered free of contamination by PbI_2?
(ksp for AgI=1.5x10^-13.. Ksp for PbI_2= 8.7x10^-9)
PLEASE HELP!! HOW DO I GO ABOUT THIS?
