The solubility product of iron (III) hydroxide is `1.6xx10^(-39)`. If x is the solubilityof iron (III) hydroxide, then which of the following expressions can be used to calculate x ?

A

`K_(sp)=x^(4)`

B

`K_(sp)=9x^(4)`

C

`K_(sp)=27x^(3)`

D

`K_(sp)=27x^(4)`

Text Solution

Verified by Experts

The correct Answer is:
D
`Fe(OH)_(3)hArr underset(x)(Fe^(3+))+underset(3x)(3OH^(-))`
`K_(sp)=(x)(3x)^(3)=27 x^(4)`.
