A complex `PtCl_(4).5NH_(3)` shows a molar conductance of 402 `ohm^(-1)cm^(2) mol^(-1)` in water and precipitate three mole of AgCl with `AgNO_(3)` . The formula of the complex is

A

` [ Pt ( NH _ 3 ) _ 6]Cl _ 4 `

B

` [Pt ( NH _ 3 ) _ 4 Cl _ 2 ]Cl _ 2 `

C

`[Pt ( NH _ 3 ) _ 5Cl]Cl _3 `

D

`[Pt ( NH _ 3 ) _3Cl_ 3]Cl `

Text Solution

Verified by Experts

The correct Answer is:
C
The complex `PICI_(4).5NH_(4)` is designated as `[Pt(NH_(3))_(5)CI]CI_(3)` which ionizes to `[Pt(NH_(3))_(5)CI]^(3+)` ions. Thus total ions produced are four but three moles of AgCl are produced from `3CI^(-)` ions with `AgNO_(3)`.-
