Question

The hydration energy of Al+3 is three times Great than that of Ca2+ why?

Answer 1

Answer:

Hydration energy depends upon charge density (Charge/size). As Al+3 charge is greater than Mg+2 so it's charge density is greater than Mg+2, that's why hydration energy of Al+3 ion is greater than Mg+2. .

Answer 2

Hydration energy depends upon charge density (Charge/size). As Al+3 charge is greater than Mg+2 so it's charge density is greater than Mg+2, that's why hydration energy of Al+3 ion is greater than Mg+2. .
