The hydration energy of Mg²⁺ is greater than that of
Options
(a) Na⁺
(b) Be²⁺
(c) Mg³⁺
(d) Al³⁺
Correct Answer:
Na⁺
Explanation:
Hydration energy depends on charge of ion and ionic radius. Higher the charge, greater the hydration energy. On the other hand, smaller the size, greater the hydration energy. Charge is considered first for comparison. Hence, Mg²⁺ has higher hydration energy than Na⁺.
