Solution
An electrolyte dissolves in water when hydration energy is greater than lattice energy.
Explanation:
The salt is water-soluble if the hydration energy is equal to or greater than the lattice energy. In salts where the hydration energy is higher than the lattice energy, solvation results in the release of energy in the form of heat.
