A 0.001 molal solution of [Pt(NH3)4cl4] in water had a freezing point depression of 0.0054∘. If Kf for water is 1.80, the correct formulation for the above molecule is
△T=i Kf m
⇒ i=△TfKf m=0.00541.80×0.001=3
Thus complex produces three ions per molecule. hence possible correct formula is
[Pt(NH3)4Cl2]Cl2
