A coordination compound `CrCI_(3).4H_(2)O` precipitates `AgCI` when treated with `AgNO_(3)` The molar conductance of its solution corresponds to a total of two ions Write the structural formula of the compound and name it .

Explanation

The molar conductance of the solution of `CrCI_(3).4H_(2)O` indicates that this compound contains one `CI^(Θ)` ion and one `Cr(H_(2)O)_(4)CI_(2)]^(o+) ion `

`CI^(Θ)` ion may be obtained a perecipitate of AgCI with `AgNO_(3)` solution
`CI^(Θ) + AgNO_(3) rarr CI darr + NO_(3)^(Θ)`
Thus the structure of the given compounds and its name is
`[Cr(H_(2)O)_(4)CI_(2)]CI`
Tetraaquadichloridochromium (III) chloride .
