Question

what is lattice enthalpy and any relation with solubility?​

Answer 1

Answer:

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.
