Greater the number of ions, greater the conductance.

(i)

K_{2} [PtCl]_{6} ⇌ three ions 2 K^{+} + [PtC l_{6}]^{2 -}

(ii)

PtC l_{4} \cdot 2 N H_{3} ⇌ [Pt (N H_{3})_{2} C l_{4}] ⟶

no ion (zero)

(iii)

[Pt (N H_{3})_{3} C l_{3}] Cl ⇌

two ions

(iv)

[Pt (N H_{3})_{5} Cl] C l_{3} ⇌

four ions (maximum)
