Answer 1

Answer:

1 chloride is present inside the coordinate sphere

Explanation:

The depression of freezing point is given by

$\boxed{\triangle T=(i ) K_f ( molality )}$

Putting in the given values of ΔT, $K_f$ and m, we get :-

$=>i=\frac{0.0558}{(1.86)(0.01)}\\\\=>i=\frac{0.0558}{0.0186}\\\\=>\boxed{i=3}$

Also since it is given that the complex behaves like a strong electrolyte, it completely dissociates in solution

∴ We get 3 ions of which one contains the coordination sphere and the remaining two are satisfied by $Cl^{-} \ ions$

Now the complex is of the form : $[Co(NH_3)_xCl_y]Cl_2$

Now balancing the oxidation state of Cobalt and chlorine ions, we see that the coordination sphere has a total charge of +2

∴ $3+x(0)+y(-1)=2\\\\=> \boxed{y=1}$

Hence one Cl atom is present inside the coordination sphere

Hope this answer helped you :)
