Chapter 11, Problem 134QP

Lead(II) iodide, ${\text{PbI}}_{\text{2}},$ is a yellow solid with a solubility of about 0.1 g/100 mL ${\text{H}}_{\text{2}}\text{O}\text{.}$ What would you expect to expect to observe if 0.3 g of solid ${\text{PbI}}_{\text{2}}$ is mixed with 250 mL of water?

A. All of the ${\text{PbI}}_{\text{2}}$ would dissolve.

B. Only 0.1 g of ${\text{PbI}}_{\text{2}}$ would dissolve.

C. About 0.05 g of yellow solid would remain undissolved.

D. The dissolved solid would exist in solution as Pb atoms and ${\text{I}}_{\text{2}}$ molecules.

E. According to the solubility rules, ${\text{PbI}}_{\text{2}}$ is insoluble so no ${\text{PbI}}_{\text{2}}$ will dissolve.
