For which of the following sparingly soluble salt, the solubility (S) and solubility product (K_(sp)) are related by the expression S=(K_(sp)??4)^(1//3)?

For which of the following sparingly soluble salt, the solubility (S)

1.	For which of the following sparingly soluble salt, the solubility (S) and solubility product (K_(sp)) are related by the expression S=(K_(sp)??4)^(1//3)?
Answer» `BaSO_(4)` `Ca_(3)(PO_(4))_(2)` `Hg_(2)Cl_(2)` `Ag_(3)PO_(4)` Solution :`BasO_(4)hArrBa^(2+)+SO_(4)^(2-),K_(sp)=S^(2) " or" S=(K_(sp))^(1//2)` `Ca_(3)(PO_(4))_(2)hArr3Ca^(2+)+2PO_(4)^(3-),K_(sp)=(3S)^(3)(2S)^(2)=108S^(5) " or" S=(K_(sp)//108)^(1//5)` `Hg_(2)Cl_(2)hArr Hg_(2)^(2+) + 2 Cl^(-), K_(sp)=S(2S)^(2)=4S^(3) " or" S=(K_(sp)//4)^(1//3)` `Ag_(3)PO_(4)hArr3Ag^(+)+PO_(4)^(3-), K_(sp)=(3S)^(3)S=27S^(4) "or" S=(K_(sp)//27)^(1//4)` `CUS hArr Cu^(2+)+S^(2-), K_(sp)=[S][S]=S^(2) "or" S=(K_(sp))^(1//2)`
