Question

Which of the following is most soluble in water ? Assume no reaction of cation/anion.
(A) MnS (Ksp = 2.5 10-13)
(B) ZnS (Ksp = 1.6 x 10-24)
(C) Bi2S3 (Ksp=1.6 x 10-72)
(D) Ag2S (Ksp = 10-51)​

Answer 1

Answer:

the substances that are miscible in the water are salt sugar and send

Explanation:

the substances that are immiscible in the water are talcum powder stones oil

Answer 2

(A) [tex]MnS\ (K_{sp} =2.5\times 10^{-13}) [/tex]

Explanation:

The solubility product of a solid is the amount of solid dissociates into its respective ions in the solution. Thus more the value of the Ksp, the more is the salt soluble in the solvent.

So,

Given that:-

[tex]MnS\ (K_{sp} =2.5\times 10^{-13}) [/tex]

[tex]ZnS\ (K_{sp} =1.6\times 10^{-24}) [/tex]

[tex]Bi_2S_3\ (K_{sp} =1.6\times 10^{-72}) [/tex]

[tex]Ag_2S\ (K_{sp} =10^{-51}) [/tex]

The salt having highest value of Ksp is MnS. So, it is most soluble.
