If two Cl^(-) ions are precipitated by A...

If two `Cl^(-)` ions are precipitated by `AgNO_(3)` from `PtCl_(4).4NH_(3)`, find formula of complex :

A

`[Pt(NH_(3))_(4)]Cl_(4)`

B

`[Pt(NH_(3))_(4)Cl_(2)]Cl_(2)`

C

`[Pt(NH_(3))_(2)Cl_(2)]Cl_(2)`

D

`[Pt(NH_(3))_(6)]Cl_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
2 mol AgCl is obtained so two `Cl^(-)` should be present in ionisation sphere. In (c ) and (b) option molecular formula is not the `PtCl_(4)84NH_(3)`

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

NaCl_((aq)) gives a white precipitate with AgNO_(3) solution but C Cl_(4) or CHCl_(3) does not , because

When a coordination complex PtCl_(4).6NH_(3) is mixed with AgNO_(3) , 4 moles of AgCl are precipitated per mole of the complex ? Write : (i) structural formula of the complex IUPACname of the complex .

NaCl and AgNO_(3) are ionic solids and they readily dissodciate to from ions in solution. Ag^(+) ions combine with Cl^(-) ions to give white precipitate of AgCl. But C Cl_(4) is covaolent compound and does not give Cl^(-) ions in solution. Therefore, no reaction is possible between C Cl_(4) and AgNO_(3).

In coordination chemistry there are a veriety of methods applied to find out the structure of complexes. One method involves treating the complex with known reagents and from the nature of reaction, the formula0 of the complex can be predicted. An isomers of the complex Co(en)_(2)(H_(2)O)Cl_(2)Br , on reaction with concentrated H_(2)SO_(4) (dehydrating agent ) it suffers loss in weight and on reaction with AgNO_(3) solution it gives a white precipitate which is soluble in NH_(3)(aq) . The correct formula of the complex is :
