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°C, the number of chloride(s) in the coordination sphere of the complex is ______ [Kt of water = 1.86 K kg mol⁻¹].

Answer 1

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°C, the number of chloride(s) in the coordination sphere of the complex is 1 [Kt of water = 1.86 K kg mol⁻¹].
