Given the following Ksp values, which statement about solubility in water is correct?

                        K  sp

PbCrO4           2.0 x 10 -16

Zn(OH)2          4.5 x 10 -17

Pb(OH)2          1.2 x 10 -15

MnS                2.3 x 10 -13

a) PbCrO4, Zn(OH)2, and Pb(OH)2 have equal solubility in water.

b) PbCrO4 has the lowest solubility in water.

c) The solubility of MnS in water will not be pH dependent.

d) MnS has the highest molar solubility in water.

e) A saturated PbCrO4 solution will have a higher [Pb2+] than a saturated Pb(OH)2 solution.
