Vedclass · Answer

(B) The solubility of alkaline earth metal hydroxides increases down the group. This is because the lattice energy decreases more rapidly than the hydration energy as the size of the cation increases from $Be^{2+}$ to $Ba^{2+}$. Therefore,$Be(OH)_2$ has a very high lattice energy,making it insoluble,while $Ba(OH)_2$ is highly soluble.

$Be(OH)_2$ is insoluble in water while $Ba(OH)_2$ is highly soluble due to:
