For sulfates:
Solubility decreases as you go down the group. The lattice dissociation enthalpy and hydration enthalpy both decrease as you go down the group . The hydration enthalpy decreases more than the lattice dissociation enthalpy. Therefore the enthalpy of solution becomes more endothermic (or less exothermic).
