Question

Amongst the following hydroxides, the one which has the lowest value of Ksp at ordinary temperature is :

Options

A.Mg(OH)2
B.Ca(OH)2
C.Ba(OH)2
D.Be(OH)2

Solution

The solubility of hydroxides of alkaline earth metal salts increases down the group from Be to Ba. This is because of the fact that down the group with increasing size of cation the hydration energy as well as lattice energy also decrease but the change in lattice energy is more as compare to that of hydration energy.
