Question

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

$\mathrm{CoCl}_{3} .6 \mathrm{NH}_{3}$ is $\left[\mathrm{Co}\left(\mathrm{NH}_{3}ight)_{6}ight] \mathrm{Cl}_{3} ightarrow 4$ ions in solution\ $\mathrm{PtCl}_{4} .5 \mathrm{NH}_{3}$ is $\left[\mathrm{Pt}\left(\mathrm{NH}_{3}ight)_{6} \mathrm{Cl}ight] \mathrm{Cl}_{3} ightarrow 4$ ions in solution\ Both give the same number of ions in aqu. solution.\
