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

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

11. 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 ?

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. K sp = 8.0 x 10 -16

14. Complexation and Solubility What is the solubility of AgCl in pure water and in 0.1 M NH 3 solution? K f (Ag(NH 3 ) 2 + = 1.1 x 10 -7 K sp = 1.8 x 10 -10 x = 0.012
