Question

Use the Solubility Rules to determine which of the following substances could be used to make a solution that is 0.1 M in Pb2+ ion. Select all that apply.

Pb(NO 3)2

PbCrO4

PbCl2

Pb(ClO4)2

PbS

PbCO

I know the solubility rules, but I can't seem to get the right ones.

Lead nitrate (the first one) and lead acetate are the only soluble lead compounds.

Lead chloride although having a Ksp of 1*10^-4 would not be great for a 0.1M solution.

the last one i think should be PbCO3 and it has a Ksp of 10^-14

and all other are above 1*10^-8 so only the first one!
