1.

The compounds that gives white precipitates with AgNO_(3).

Answer»

`[Co(NH_(3))_(6)]Cl_(3)`
`[Co(NH_(3))_(3)Cl_(3)]`
`K_(2)[PT(en)_(2)Cl_(2)]`
`[FE(en)_(3)]Cl_(3)`

Solution :`[Co(NH_(3))_(6)]Cl_(3)+3AgNO_(3)to3AgCldarr+[Co(NH_(3))_(6)](NO_(3))_(3)`
`[Fe(en)_(3)]Cl_(3)+3AgNO_(3)toAgCldarr[Fe(en)_(3)](NO_(3))_(3)`
The COMPLEX is which `CL^(-)` ions present outside the []can give white ppt with `AgNO_(3)` solution.
