Question

Which of the following factors affects the hydration energy of an ion?

• A. Hydration energy depends on charge of the ion
• B. Hydration energy depends on the ionic radii
• C. Hydration energy depends on the mass of the ion
• D. Both A and B

Answer 1

The correct option is D Both A and B

Hydration energy of an ion is directly proportional to the charge of the ion and inversly proportional to its ionic radii.
Thus, higher the charge to size raio i.e charge density, higher will be the hydration energy.
