Question

If the freezing point of a 0.01 molal aqueous solution of a cobalt (III) chloride-ammonia complex (which behaves as a strong electrolyte) is

- {0.0558}^{o}C

, the number of chloride(s) in the coordination sphere of the complex is

[ {K}_{f}ofwater = 1.86Kkgmo{l}^{- 1} ]

Correct answer: 1

∆ T _ f = K _ f × i × m 0.0558 = 1.86 × i × 0.01 i = 3 Given complex behaves as a strong electrolyte α = 100% n = 3 (no. of particles given by complex) ∴ complex is [Co (N H _ 3 ) _ 5 Cl]C l _ 2 no. of C l ^ - ions in the co-ordination sphere of the complex = 1
