The solubility products of `AI(OH)_(3)` and `Zn(OH)_(2)` are `8.5xx10^(-23)` and `1.8xx10^(-14)` respectively. If `NH_(4)OH` is added to a solution containing `AI^(3+)` and `Zn^(2+)` ions, then substance precipitated first is:

A

`AI(OH)_(3)`

B

`Zn(OH)_(2)`

C

both together

D

none at all

Text Solution

Verified by Experts

The correct Answer is:
A
Solubility of `AI(OH)_(3)` is lesser than `Zn(OH)_(2)`.
