Question

Ques.19) (i) A coordination compound with the molecular formula CrCl₃. 4H₂O precipitates AgCl with AgNO₃ solution. Its molar conductivity is found to be equivalent to two ions. What is the structural formula of the compound ?

Open in App

Solution

1. If the molar conductivity is found to be of only two ions then, there exists only one cation and one anion.

2. Thus the structural formula of coordination compound is:

[Cr(H₂O)₄Cl₂]Cl

3. The corresponding ions are: [Cr(H₂O)₄Cl₂]⁺ and Cl^-.
