1. Solubility and Complexation Equilibria
Chapter 18

7. Common Ion Effect: The presence of an ion common to a
solubility equilibria will decrease solubility of the salt.
What is the solubility of PbCl2 in a M NaCl solution?

8. Complexation Reactions and Equilibria

10. What is the [Cu2+] in a solution that starts out as 0.100 M Cu(NH3)42+?

11. What is the [Cu2+] in a solution that starts out as 0
What is the [Cu2+] in a solution that starts out as M Cu(NH3)42+ but is also M in NH3?

12. Simultaneous Equilibria
Effect of pH on solubility of metal hydroxides
Using complexation reactions to dissolve salts

13. pH and Solubility of Metal Hydroxides
What is the solubility of Fe(OH)2 in pure water, pH = 7 buffer,
and pH = 9 buffer.
Ksp = 8.0 x 10-16

14. Complexation and Solubility
What is the solubility of AgCl in pure water and in
0.1 M NH3 solution?
Kf(Ag(NH3)2+ = 1.1 x 10-7
Ksp = 1.8 x 10-10
x = 0.012
