Question

Beso4 is soluble but baso4 not and beo is not soluble but bao is soluble why ???

Answer 1

(i) Lattice energy of BeO is greater than its hydration energy so, it is insoluble in water while in case of BeSO4 , hydration energy is greater than lattice energy, so, it is readily soluble in water. (ii) Lattice energy of BaO is much smaller than that of its hydration energy, so it is soluble in water .
