1.

The co-ordination compound of which one of the following compositions will produce two equivalents of AgCl on reaction with aqueous silver nitrate solution

Answer»

`CoCl_(3).3NH_(3)`
`CoCl_(3).6NH_(3)`
`CoCl_(3).4NH_(3)`
`CoCl_(3).5NH_(3)`

Solution :The chloride ions which are present in the ionisation sphere GET precipitated as `AgCl` on reaction with `AgNO_(3).` THUS depending on the number of chloride present in the ionisation sphere will determine the no. of equivalents of AgCl produced.
`[Co(NH_(3))_(5)Cl]Cl_(2)+2AgNO_(3)RARR[Co(NH_(3))_(5)Cl](CO_(3))_(2)+2AgCl.`
