Marks: +1, -0
The pair [Co(NH3)4Cl2]Br2[\mathrm{Co}(\mathrm{NH}_3)_4\mathrm{Cl}_2]\mathrm{Br}_2 and [Co(NH3)4Br2]Cl2[\mathrm{Co}(\mathrm{NH}_3)_4\mathrm{Br}_2]\mathrm{Cl}_2 will show
Solution:  
[Co(NH3)4Cl2]Br2→[Co(NH3)4Cl2]++2Br−[\mathrm{Co}(\mathrm{NH}_3)_4\mathrm{Cl}_2]\mathrm{Br}_2 \rightarrow [\mathrm{Co}(\mathrm{NH}_3)_4\mathrm{Cl}_2]^{+} + 2\mathrm{Br}^{-}
[Co(NH3)4Br2]Cl2→[Co(NH3)4Br2]++2Cl−[\mathrm{Co}(\mathrm{NH}_3)_4\mathrm{Br}_2]\mathrm{Cl}_2 \rightarrow [\mathrm{Co}(\mathrm{NH}_3)_4\mathrm{Br}_2]^{+} + 2\mathrm{Cl}^{-}
