Question 1

Using the following reduction potentials for copper determine the unstable copper compound.
Cu+(aq) + e- → Cu(s)E° = +0.52 V
Cu2+(aq) + e- → Cu+(aq)E° = +0.15 V

◦ CuSO4
◦ Cu(OH)2
◦ CuCl2
◦ CuCl

Question 2

Describe what happens when 3.0 M NH3 is slowly added to an aqueous solution of CuSO4.
◦ A blue precipitate of Cu(OH)2 is formed which is then converted to the royal blue complex [Cu(NH3)4]2+.
◦ A blue precipitate of Cu(OH)2 forms.
◦ A royal blue complex of [Cu(NH3)4]2+ is formed which then is converted to a blue precipitate of Cu(OH)2.
◦ A royal blue complex of [Cu(NH3)4]2+ is formed.
