The molar solubility (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»

`s = (256 K_(sp))^(1//5)`
`s = (128 K_(sp))^(1//4)`
`s = (K_(sp)//128)^(1//4)`
`s = (K_(sp)/256)^(1//5)`

SOLUTION :`{:(MX_(4),rarr,M+,4X,,K_(sp) = (4s)^(4)s, K_(sp) = 256s^(5)),(,,S,4S,):}`
`s = ((K_(sp))/(256))^(1//5)`.
