A solution contains 0.022 M Ag and 0.033 M Pb2 . If you add Cl–, AgCl and PbCl2 will begin to precipitate. What is the concentration of Cl– required, in molarity, when
A. AgCl precipitation begins?
B. AgCl precipitation is 99.99% complete?
C. PbCl2 precipitation begins?
D. PbCl2 precipitation is 99.99% complete?
Finally, give the concentration range of Cl– for the complete separation of Ag and Pb2 .
E. Concentration of Cl– at the start: F. Concentration of Cl– once complete

For A I got 8.18x10^-9 and for B I got 0.0227. A is wrong but I'm not sure why..? and I need help on how to approach the rest of this question please! Really confused.
