Answer 1

Answer:

$\huge{\underbrace{\overbrace{\mathfrak{\pink{Answer:}}}}}$

Answer

When BeO is dissolved in water, the hydration energy of its ions is not sufficient to overcome the high lattice energy. Therefore, BeO is insoluble in water. On the other hand, sulphate ion is a large anion. Thus, the lattice energy of BeSO

4

is not very high and so it is soluble in water. Hence, Lattice energy of BeO is higher than BaO due to small size of Be

2+

and its covalent nature

• BeO has a very high lattice enthalpy due to the high charge and small ionic radii of the Be2+and O2− ions. Its lattice
