Question:
A coordination compound CrCl3.4H2O precipitates silver chloride when treated with silver nitrate. The molar conductance of its solution corresponds to a total of
two ions. Write the structural formula of the compound and name it.
Solution:
If it forms silver chloride then there is one free chlorine atom outside the coordination sphere. The structural formula has to be [Cr(H2O)4Cl2]Cl. The name of this complex is tetraaquadichlorido chromium(III) chloride.
