A 0.001 molal solution of `[Pt(NH_(3))_(4)CI_(4)]` in water had a freezing point depression of `0.0054^(@)C`. If `K_(f)` for water is `1.80`, the correct formulation for the above molecule is

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

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

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

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

Text Solution

Verified by Experts

The correct Answer is:

`DeltaT_(f)=imk_(f),0.0054=ixx1.8xx0.001`
i = 3 so it is `[Pt(NH_(3))_(4)Cl_(2)]Cl_(2)`.
