Which one of the following does not give a white precipitate with silver nitrate solution?
[Co(NH3)5Cl]Cl2
[Co(NH3)4Cl2]Cl
[Co(NH3)3Cl3]
[Co(NH3)6]Cl3
For the precipitation of AgCl there must be free Cl- ion, the Cl- ligand have to be there in the primary coordination sphere.
Arrange the following complexes in the increasing order of conductivity of their solution [Co(NH3)3Cl3],[Co(NH3)4Cl2]Cl,[Co(NH3)6]Cl3,[Co(NH3)5Cl]Cl2
