Which one of the following does not give a white precipitate with silver nitrate solution?

View answer and explanation

Correct option: D

\left[ {\mathrm{Co}{{\left( {\mathrm{N}{\mathrm{H}_3}} \right)}_3}\mathrm{C}{\mathrm{l}_3}} \right]

Option D (

\left[ {\mathrm{Co}{{\left( {\mathrm{N}{\mathrm{H}_3}} \right)}_3}\mathrm{C}{\mathrm{l}_3}} \right]

) is correct because in this complex, all the chloride ions are coordinated inside the coordination sphere and hence do not ionize to give free chloride ions that can react with silver nitrate to form a white precipitate.
