Vedclass · Answer

(D) The hydration energy decreases as the size of the alkaline earth metal cation increases down the group.$Mg^{2+}$,$Ca^{2+}$,and $Sr^{2+}$ ions have smaller sizes and higher charge density,allowing them to form hydrated salts like $Mg(NO_3)_2 \cdot 6H_2O$,$Ca(NO_3)_2 \cdot 4H_2O$,and $Sr(NO_3)_2 \cdot 4H_2O$.Due to the relatively large size of the $Ba^{2+}$ ion,its hydration energy is insufficient to hold water molecules in the crystal lattice,so $Ba(NO_3)_2$ crystallizes as an anhydrous salt.
