Answer:
When a coordination compound CoCl
3
.6NH
3
is mixed with AgNO

, 3 moles of AgCl are precipitated per mole of the compound. This indicates that in the coordination compound, all the three chlorine atoms are in the ionisation sphere and six ammonia molecules are in the coordination sphere.
(i) Structural formula of the complex is [Co(NH
3
)
6
]Cl
