Explanation / Answer
Ksp of BaCO3 = 5.0 x 10^-9
Ksp of PbCO3 = 7.4 x 10^-14
here Ksp of PbCO3 < Ksp of BaCO3.
so BaCO3 is more soluble.
BaCO3 --------------> Ba+2 + CO32-
Ksp = [Ba+2][CO32-]
5 x 10^-9 = S^2
S = 7.07 x 10^-5 M
solubility of BaCO3 = 7.07 x 10^-5 M
solubility of PbCO3 = 2.72 x 10^-7 M
so BaCO3 is more soluble.
