1. Part A

A saturated solution of barium fluoride, BaF2, was prepared by dissolving solid BaF2 in water. The concentration of Ba2+ ion in the solution was found to be 7.52×10?3M . Calculate Ksp for BaF2.

Part B

The value of Ksp for silver carbonate, Ag2CO3, is 8.10×10?12. Calculate the solubility of Ag2CO3 in grams per liter.

2. The generic metal hydroxide M(OH)2 has Ksp = 9.05×10?18. (NOTE: In this particular problem, because of the magnitude of the Ksp and the stoichiometry of the compound, the contribution of OH? from water can be ignored. However, this may not always be the case.)

Part A

What is the solubility of M(OH)2 in pure water?

Part B

What is the solubility of M(OH)2 in a 0.202 M solution of M(NO3)2?

Consider the dissolution of AB(s): AB(s)⇌A+(aq)+B−(aq) Le Châtelier's principle tells us that an increase in either [A+] or [B−] will shift this equilibrium to the left, reducing the solubility of AB. In other words, AB is more soluble in pure water than in a solution that already contains A+ or B− ions. This is an example of the common-ion effect.

An aqueous solution of sodium fluoride is slowly added to a water sample that contains barium ion (4.15×10-2 M ) and calcium ion (3.55×10-2 M ). The Ksp of barium fluoride is 1.00x10–6. The Ksp of calcium fluoride is 3.90x10–11. What is the remaining concentration of the first ion to precipitate when the second ion begins to precipitate?
