The molar solubility (in mol `L^(-1) ) ` of a sparingly soluble salt `MX_4` is 's' The corresponding solubility product is `K_(sp)` .s is given in terms of `K_(sp)` by the relation.

Answer

D

Explanation

`MX_(4) to M^(4+) + 4X^(-)`
s
s 4s
`K_(sp)=(s)(4s)^(4) = 256S^(5) implies s=(K_(sp)/256)^(1//5)`
