Both ${\mathrm{Co}}^{3+}$and ${\mathrm{Pt}}^{4+}$ have a co-ordination number of six, which of the following pair of complexes will show approximately the same electrical conductance for their 0.001M aqueous solution?

Both ${\mathrm{CoCl}}_3.6{\mathrm{NH}}_3$ and ${\mathrm{PtCl}}_4.5{\mathrm{NH}}_3$ will have the same electrical conductance for their 0.001 M aqueous solutions because they produce the same amount of ions upon dissociation.

$CoC{l}_3.N{H}_3\to \left[Co\right(N{H}_3{)}_6{\left]}^{\right(}3+)+3C{l}^{-}$

$PtC{l}_4.5N{H}_3\to \left[Pt\right(N{H}_3{)}_{5}C{l}^{(}3+)+3C{l}^{-}$
