202-NYB-05: Course Notes ProblemsChapter 16: Solubility and Complex ion Equilibria. (Zumdahl/Zumdahl, 10th Ed)
Problem 1: Copper(I) bromide (CuBr) has a measured solubility of 2.0 x 10-4 M
at 25°C. Calculate its Ksp value.
Problem 2: Calculate the Ksp value for bismuth sulphide (Bi2S3), which has a
solubility of 1.0 x 10-15 M at 25°C.
Problem 3: The Ksp value for copper(II) iodate, Cu(IO3)2, is 1.4 x 10-7 at 25°C.
Calculate its solubility at 25°C.
Problem 4: Calculate the solubility of solid CaF2 (Ksp = 4.0 x 10-11) in a 0.025 M
NaF solution.
Problem 5: A solution is prepared by adding 750.0 mL of 4.00 x 10-3 M Ce(NO3)3
to 300.0 mL of 2.00 x 10-2 M KIO3. Will Ce(IO3)3 (Ksp = 1.9 x 10-10) precipitate
from this solution?
Problem 6: A solution contains 1.0 x 10-4 M Cu+ and 2.0 x 10-3 M Pb2+. If a
source of I- is added gradually to this solution, will PbI2 (Ksp = 1.4 x 10-8) or CuI
(Ksp = 5.3 x 10-12) precipitate first? Specify the concentration of I- necessary to
begin precipitation of each salt.
