    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!
