Both Co^(3+) and 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 ?

Answer»

`CoCl_(3).4NH_(3)" and " PtCl_(4).4NH_(3)`
`CoCl_(3).3NH_(3)" and " PtCl_(4).5NH_(3)`
`CoCl_(3).6NH_(3)" and " PtCl_(4).5NH_(3)`
`CoCl_(3).6NH_(3)" and " PtCl_(4).3NH_(3)`

SOLUTION :`CoCl_(3)*6NH_(3)rarr [CO(NH_(3))_(6)]Cl_(3)`
`PtCl_(4)*5NH_(3)rarr[PT(NH_(3))_(5)Cl]Cl_(3)`
Both have 4 ions in their aq. Solution
