which of the folllowing coordination compound will give precipitate with an aqueous solution of `AgNO_(3)` ?

A

`[CR(NH_(3))_(6)]Cl_(3)`

B

`[Cr(NH_(3))_(3)Cl_(3)`]

C

`[Cr(NH_(3))_(5)Cl]SO_(4)`

D

`Na_(3)[Cr(CN)_6)]` .

Text Solution

Verified by Experts

The correct Answer is:
A
In the complex , three `Cl^(-)` ions are present Outside the co-ordinate sphere . They will acept three moles of `AgNO_(3)` to form three moles of AgCl as while precipitate. `[Cr(NH_(3))_(6)]Cl_(3)+ 3AgNO_(3) rArr [Cr(NH_(3))_(6)](NO_(3))_(3) + 3 AgCl` (white ppt.)
