Detailed Solution

When a coordination compound CoCl₃.6NH₃ is mixed with AgNO₃, 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 ionization sphere and six ammonia molecules are in the coordination sphere.

(i) Structural formula of the complex is [Co(NH₃)₆]Cl₃
The formation of AgCl is as represented
[Co(NH₃)₆]Cl₃+3AgNO₃→[Co(NH₃)₆]₃⁺+3NO₃⁻+3AgCl↓
so both the statements are true
