#1

A coordination compound $CrCl_{3}$ • 4$H_{2}O$ 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.


#2

Formation of white precipitate with $AgNO_{3}$ shows that atleast one ${{Cl}^{-}}$ ion is present outside the coordination sphere. Moreover only two ions are obtained in solution, so only one ${{Cl}^{-}}$ is present outside the sphere.
Thus, IUPAC name is tetraaquadichloridocobalt (III) chloride.
