Question

What is the oxidation number and the coordination number of the metal? Oxidation Number Coordination Number [Cu(NH_3)_4]SO_4 middot H_2O_____________[Co(NH_3)_5H_2O]Cl_3____________[Co(NH_3)_5Cl]Cl_2_______________[Ni(NH_3)_6]Cl_2_____________How many TOTAL SPECIES, not including water, would be present in water solutions of the complexes from #1? 'Chemical species' include atoms, molecules, and ions. What are they?_________________________________________________________________what evidence are we using to determine if the liqands are labile or inert?

Explanation / Answer

a)[Cu(NH3)4]SO4*H2O

Metal Oxidation no=2+ , metal coordination no=4

b)

[CO(NH3)5H2O]Cl3

Metal Oxidation no=3+ , metal coordination no=6

c)

[CO(NH3)5Cl]Cl2

Metal Oxidation no=3+ , metal coordination no=6

d)

[Ni(NH3)6]Cl2

Metal Oxidation no=2+ , metal coordination no=6
