A 1.00 L solution at 25˚C containing both 0.0020 M Ba2+ and 0.0020 M Pb2+.

A solution containing dissolved SO42– is slowly added to the solution containing 0.0020 M Ba2+ and 0.0020 M Pb2+.

a) Which salt will precipitate first, BaSO4 or PbSO4? Briefly explain your answer.

b) Calculate the concentration of SO42– that must be added to create a saturated solution with 0.0020 M Pb2+. (Ignore Ba2+.)

c) T or F The Ksp value of PbSO4 will increase as the temperature of the solution increases.

The cations Pb2+(aq) and Ba2+(aq) can be precipitated as almost insoluble sulfates. The Ksp values for PbSO4(s) and BaSO4(s) are 2.5 × 10−8 and 1.1 × 10−10, respectively. If you have a solution that is 0.010 mol L-1 in both Pb2+(aq) and Ba2+(aq) ions, and the concentration of SO42-(aq) ions is gradually increased, the less soluble salt will precipitate first. What is the concentration of the cation (Pb2+ or Ba2+) that precipitates first remains in solution just before the second...

Ba2+ is added to a solution to precipitate sulfate as BaSO4 (Ksp = 1.1 x 10-10). a. The concentration of [Ba2+] is raised to 0.0020 M and solid BaSO4 is present in the system; calculate the equilibrium concentration of SO42-. b. Suppose KCl is added to the system to increase the ionic strength to 0.100 M; calculate the activity of the Ba2+ in this solution. c. Is equilibrium [SO42-] increased, decreased or unchanged by the addition of KCl ?

Can Ba2+ be separated from Pb2+ by the addition of Na2SO4? Assume the starting solution is 0.10 M in both cations and use whatever concentration of sulfate you like. (Ksp of PbSO4 = 1.3 x 10-8), while that of( BaSO4 = 1.5 x 10-9). Calculate how much of the first cation to precipitate is left in solution when the second starts to fall out of solution. Is it less than 1% of the initial present?
