In aqueous solution$\left(\text{0}\text{.001}\text{M}\right)$, then complexes with dissociate to give the ions :
$\text{[Pt}{({\text{NH}}_{\text{3}})}_{\text{6}}{\text{Cl}}_{\text{4}}]\rightleftharpoons {[\text{Pt}{({\text{NH}}_{\text{3}})}_{\text{6}}]}^{\text{4+}}\text{+}{\text{4Cl}}^{-}\text{;}\text{5}\text{ions}$
${\text{[Cr(NH}}_{\text{3}}{\text{)}}_{\text{6}}{\text{]Cl}}_{\text{3}}\rightleftharpoons {[\text{Cr}{({\text{NH}}_{\text{3}})}_{\text{6}}]}^{\text{3+}}\text{+}{\text{3Cl}}^{-}\text{;}\text{4}\text{ions}$
${\text{[Co(NH}}_{\text{3}}{\text{)}}_{\text{4}}{\text{Cl}}_{\text{2}}\text{]Cl}\rightleftharpoons {{\text{[Co(NH}}_{\text{3}}{\text{)}}_{\text{4}}{\text{Cl}}_{\text{2}}\text{]}}^{\text{+}}\text{+}{\text{Cl}}^{\text{-}}\text{;}\text{2}\text{ions}$
${\text{K}}_{\text{2}}{\text{[PtCl}}_{\text{6}}\text{]}\rightleftharpoons {\left[{\text{PtCl}}_{\text{6}}\right]}^{\text{2}-}{\text{+2K}}^{\text{+}}\text{;}\text{3}\text{ions}$
