What is the most soluble salt of the following set? What is the most soluble salt of the following set?
(A) Sn(OH)2 with Ksp = 1.6 × 10-19
(B) Al(OH)3 with Ksp = 1.9 × 10-33
(C) AgCN with Ksp = 6.0 × 10-17
(D) Fe(OH)3 with Ksp = 2.6 × 10-39

Respuesta :

Answer:

(c) [tex]AgCN\ (K_{sp} =6.0\times 10^{-17})[/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]Sn(OH)_2\ (K_{sp} =1.6\times 10^{-19})[/tex]

[tex]Al(OH)_3\ (K_{sp} =1.9\times 10^{-33})[/tex]

[tex]AgCN\ (K_{sp} =6.0\times 10^{-17})[/tex]

[tex]Fe(OH)_3\ (K_{sp} =2.6\times 10^{-39})[/tex]

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