A salt `M_(2) X_(3)` dissolves in water such that is solubility is `x.g."mole"//litre`. Its `K_(SP)` is:

A

`x^(5)`

B

`6x^(2)`

C

`108x^(5)`

D

`6x^(5)`

Text Solution

Verified by Experts

The correct Answer is:
C
Solubility of `M_(2)X_(3)=x g "mole"//litre`
`M_(2)X_(3)hArr2M^(+3)+3X^(-2)`
`:. [M^(+3)]=2x`
`[X^(-2)]=3x`
Solubility product `K_(SP)=(2x)^(2).(3x)^(3)=108x^(5)`
