Question

When 1 mole of [Co(NH3 ) 3 Cl3 ] is added to excess of AgNO3 solution the weight of AgCl precipitated

Answer 1

Weight of AgCl precipitate is "zero"

Answer 2

No AgCl is precipitate.

• The given complex is $[Co(NH_3)_3Cl_3]$.
• In this complex, the Co atom is attached to three ammonia ligands and three Cl ligands.
• Here all the Cl atoms are present in the coordination sphere and no Cl atom is free to react so if we add silver nitrate to this complex no reaction takes place and no precipitation of AgCl or silver chloride forms.
