Weakest base among KOH, NaOH CaF(OH)(2) ...

Weakest base among KOH, `NaOH CaF(OH)_(2) and Zn (OH)_(2)` is

A

`Ca(OH)_(2)`

B

KOH

C

NaOH

D

`Zn(OH)_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`K_(b)` value for bases (Hydroxides) generally increases down the group and decreases along with the period. So dissociation of `Zn(OH)_(2)` is less. So it is weak base among the givn
