Question

[VISUAL]

  1. Equimolar samples of Pb(OH)2(s), PbI2(s), and PbF2(s) are placed in three separate beakers, each containing 250 mL of water at 25°C. After the solutions are stirred, solid remains in the bottom of each beaker. Based on the Ksp values for the compounds listed in the table above, a solution of which of the compounds will have the lowest [Pb2+] ?
A.

Pb(OH)2(s)

✓ Correct
B.

PbI2(s) only

C.

PbF2(s) only

D.

Both PbI2(s) and PbF2(s) will produce solutions with the same, lowest [Pb2+].
