Amongest the following hydroxides, the one which has the lowest value of `K` sp at ordinary temperature is:

A

`Mg(OH)_(2)`

B

`Ca(OH)_(2)`

C

`Ba(OH)_(2)`

D

`Be(OH)_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
The solubility increases down the group due to increase in size of the ion and decrease in lattice energy. Lower the solubility, lower is the `K_(sp)`.
