Question

1.) At a certain temperature the Ksp of Ag2SO4 is 1.73 x 10-5. What is the molar soliubility of silver sulfate in water in units of M (mol/liter).

2.) The Ksp of BaCO3 is 5.0 x 10-9. What is the soliubility of barium carbonate in a solution that contains 1.27 M of Na2CO3?

3.) At a ceratin temperature ths solubility of Ca3(PO4)2 is 1.52 x 10-6M. What is the Ksp at this temperature?

4.) In a titration of a 100.0mL 1.00M NH3 solution with 1.00M HCl, what is the pH of the solution after the addition of 136 mL of HCl? Kb = 1.8 x 10-5 for NH3

5.) In a titration of a 100.0mL 1.00M NH3 solution with 1.00M HCl, what is the pH of the solution after the addition of 35.3 mL of HCl? Kb = 1.8 x 10-5 for NH3

Explanation / Answer

1)Let X be the solubility of silver sulfate in in water mol/L
then from Ag2SO4 ---> 2Ag+ + SO4-2
[SO4--]=X and [Ag+]=2X
Ksp = [Ag+]^2 * [SO4--] = (2X)2 * X = 4X3 = 1.73 x 10-5
and X = 0.0258 M
