Lattice Energy

Questions given below are based on the following values of hydration energy and lattice energy. Li^(+) " " -499 " " Na^(+) " " -390 K^(+) " " -305 " " Cl^(-) " " -382 Lattice energy DeltaH_(U) (kJ mol^(-1) ) LiCl " "-840 NaCl " " -776 KCl " " -703 Which salt can be used for control humidity ?

The solubility of most salts depends on the lattice energy of the solid and the hydration energy of the ions. On descending the group, the hydration energy decreases more rapidly than the lattice energy, hence the compound become less soluble as the metals gets larger. however, with the fluorides and hydroxides and the lattice energy decreases more rapidly than the hydration energy and so their solubility increases on descending the group. Q. Which of the following is correct order of solubility of sulphates of alkaline earth metals?
