The solubility product of a sparingly so...

The solubility product of a sparingly soluble salt `AB` at room temperature is `1.21xx10^(-6)`. Its molar solubility is

A

`1.21 xx 10^(-6)`

B

`1.21 xx 10^(-3)`

C

`1.1 xx 10^(-4)`

D

`1.1 xx 10^(-3)`

Text Solution

Verified by Experts

The correct Answer is:
D
AB is binary electrolyte.
`S = sqrt(K_(sp)) = sqrt(1.2 xx 10^(-6)) = 1.1 xx 10^(-3) M`.
