2. Solid Nal is slowly added to a solution that is 0.0050 M Pb²+ and 0.0050 M Agt. Will Pb1₂ or AgI precipitate first? Specify the concentration of necessary to begin precipitation. The Koƒ Pb¹₂= 1.4 X 10˚ and the K„of AgI = 8.3 X 10-¹7

A 0.20 M sodium chloride solution is slowly added to a solution containing 0.40 M Pb2* and 0.40 M Ag* ions. What is the remaining concentration of the first ion at the point where the second ion just begins to precipitate? The Ksp of PbCl2 is 1.2x10-5, and the Ksp of AgCl is 1.8x10-10. 1.6x10-6 M 6.0x10-9 M ) 3.1x10-2 M 1.4x10-2 M 3.4x10-5 M
