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

Solubility of hydroxider of group 2 elements increases down the group. Thererfore `Be(OH)_(2)` has lowest solobility and hence lowest solubility product.
