A formulation scientist compares BaSO4\text{BaSO}_4 and CaSO4\text{CaSO}_4 as insoluble fillers. At 25°C: Ksp(BaSO4)=1.1×10−10K_{sp}(\text{BaSO}_4)=1.1\times10^{-10} and Ksp(CaSO4)=2.4×10−5K_{sp}(\text{CaSO}_4)=2.4\times10^{-5} for MSO4(s)⇌M2++SO42−\text{MSO}_4(s) \rightleftharpoons \text{M}^{2+} + \text{SO}_4^{2-}. Which statement best explains the solubility difference observed in water?
