Their solubility, however, decreases as we move down the group because their hydration energies decrease more rapidly than the lattice energies. On moving down the group, their solubility decreases. Even ignoring entropy (to a first approximation we might assume that the entropy change is constant for all the metals), solubility depends on both lattice energy and hydration enthalpy so you can't just look at one trend.
