Q. Consider the following complexes :
(i) $K _{2} PtCl _{6}$
(ii) $PtCl _{4} \cdot 2 NH _{3}$
(iii) $PtCl _{4} \cdot 3 NH _{3}$
(iv) $PtCl _{4} \cdot 5 NH _{3}$
Electrical conductances of aqueous solutions (i), (ii), (iii) and (iv) are respectively

Coordination Compounds

Solution:

Greater the number of ions, greater the conductance.

(i) $K _{2}[ PtCl ]_{6} \rightleftharpoons \underbrace{ 2K^+ +[PtCl_6]^{2-} }_{\text{three ions}}$

(ii) $PtCl _{4} \cdot 2 NH _{3} \rightleftharpoons\left[ Pt \left( NH _{3}\right)_{2} Cl _{4}\right] \longrightarrow $ no ion (zero)

(iii) $\left[ Pt \left( NH _{3}\right)_{3} Cl _{3}\right] Cl \rightleftharpoons$ two ions

(iv) $\left[ Pt \left( NH _{3}\right)_{5} Cl \right] Cl _{3} \rightleftharpoons$ four ions (maximum)
