CompoundPdCl4.6H2Ois a hydrated complex; 1 molal aqueous solution of it has freezing point 269.28 K. Assuming 100% ionization of complex, calculate the molecular formula of the complex
(Kffor water = 1.86 K kgmol-1)

Options:

Answer:
C
Solution:

ΔT=i×Kf×m
(273-269.28)=i×1.86×1
3.72=i×1.86
i=2
α=i-1n-1
1=2-1n-1
orn=2
Thus, the complex should give two ions in the solution, i.e., the complex will be[Pd(H2O)3Cl3]Cl.3H2O.
