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 PbCl 2 in a 0.200 M NaCl solution?

8. Complexation Reactions and Equilibria

12. What is the [Cu 2+ ] in a solution that starts out as 0.100 M Cu(NH 3 ) 4 2+ ?

13. What is the [Cu 2+ ] in a solution that starts out as 0.100 M Cu(NH 3 ) 4 2+ but is also 0.100 M in NH 3 ?
