Question
PtCl4. 6H2O can exist as a hydrated complex 1 molal aq. solution has depression in freezing point of 3.72o. Assume 100% ionisation and Kf(H2O) = 1.86o mol-1 kg, then complex is -
Options
A.[Pt(H2O)6]Cl4
B.[Pt(H2O)4Cl2]Cl2 . 2H2O
C.[Pt(H2O)3Cl3]Cl . 3H2O
D.[Pt(H2O)2Cl4]. 4H2O
Solution
ᐃTf = i × m × kf
i =
= 2
So salt is (Pt (H2O)3 Cl3) Cl. 3H2O.
i =
= 2So salt is (Pt (H2O)3 Cl3) Cl. 3H2O.
