Another complex studied by Werner has a composition corresponding to the formula `PtCI_(4)` . 2KCI. Form electrical conductance measurements, he determine that each formula unit contained three ions. He also found tat silver nitrae did not give a precipitate of AgCI with this complex. Which of the following formula fot this complex agrees with this information ?

A

`Pt[K_(2)CI_(6)]`

B

`K_(2)[PtCI_(6)]`

C

`K_(2)[PtCI_(4)]CI_(2)`

D

`[K_(2)PtCI_(2)]CI_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
Since `AgNO_(3)` did not given a precipitate of AgC1 with this complex, all the chlorines are securely attached to the Pt metal atom : `K_(2)[PtC1_(6)] rarr 2K^(+) + [PtC1_(6)]^(2-)`
