What is the most soluble salt of the following set? What is the most soluble salt of the following set?

DiKsa [7]

Answer:

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:-

$Sn(OH)_2\ (K_{sp} =1.6\times 10^{-19})$

$Al(OH)_3\ (K_{sp} =1.9\times 10^{-33})$

$AgCN\ (K_{sp} =6.0\times 10^{-17})$

$Fe(OH)_3\ (K_{sp} =2.6\times 10^{-39})$

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

What is the volume of a sample of liquid mercury that has a mass of 76.2g, given that the density of mercury is 13.6g/mL?

nignag [31]

Hey there!

D = m / V

13.6 = 76.2 / V

V = 76.2 / 13.6

V = 5.602 mL
