Which ion will have a maximum value of the heat of hydration?
Correct answer: A. Al+3
- A. Al+3
- B. Cs+
- C. Ba+
- D. Mg+2
Explanation
The heat of hydration depends upon the charge to size ratio of the ions. Since the charge of the 'Al ion' is the greatest, it has the maximum hydration energy.

About Lattice Energy
Lattice energy describes the energy released when gaseous ions form one mole of an ionic solid, or the energy required to separate that solid into gaseous ions, depending on the convention used. Its value depends mainly on ionic charge and radius and is calculated through Born-Haber cycles.
