Text Solution

Verified by Experts
The correct answer is:
A

Lattice energy is the amount of energy required to separate a mole of an ionic crystal into its ions and hydration energy is the amount of energy liberated when one mole of ion gets hydrated. So, for the solubility of a solid in a liquid, hydration energy must be greater than lattice energy.
