Question 1

Using the stepwise formation constants given, calculate the net formation constant for the [Cu(H2NCH2CH2NH2)2]2+ complex.

Cu2+ + en→ [Cu(en)]2+K1 = 5.2 × 1010
 [Cu(en)]2+ + en → [Cu(en)2]2+K2 = 2.0 × 109

◦ 2.6 × 101
◦ 2.5 × 109
◦ 5.4 × 1010
◦ 7.9 × 1019
◦ 1.0 × 1020

Question 2

What is the approximate concentration of free Cu2+(aq) remaining at equilibrium in a solution prepared by mixing 5.0 mL of 0.10 M CuCl2(aq) with 5.0 mL of 2.0 M aqueous ethylenediamine? [The net formation constant for the bis(ethylenediaminecopper(II) ion is 1 × 1020.]
◦ 9 × 10-22 M
◦ 7 × 10-22 M
◦ 2 × 10-22 M
◦ 1 × 10-21 M
◦ 6 × 10-22 M
