The molar solubility in mol. lit^(-1) of a sparingly soluble salt MX_(

1.	The molar solubility in mol. lit^(-1) of a sparingly soluble salt MX_(4), is S. The corresponding solubility product K_(sp), is given by the relation
Answer» `S= (K_(sp)//128 ) ^(1//4)` ` S= (218 K_(sp))^(1//4)` ` S= (256 K_(sp) )^(1//5)` ` S= (K_(sp) //256 )^(1//5) ` SOLUTION :` MX_4 hArr underset(S) M^(4+)+ 4underset( 4S) X^(-)` ` K_(sp) =[M^(4+ ) ][X^(-)] ^(4) = S( 4S)^(4) =256 S^(5) ` ` S = (K_(sp ) // 256) ^(1//5) `
