Amongest the following hydroxides, the which has the lowest value of `K_(sp)` at ordinary temperature (about `25^(@)C`) is

A

`Ca (OH)_(2)`

B

`Mg(OH)_(2)`

C

`Sr(OH)_(2)`

D

`Be(OH)_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
As the solubility of hydroxides of IIA group elements increases from Be to Ba, solubility product also increases from Be to Ba. So `Be(OH)_(2)` has lowest Ksp value
