A coordination compound with molecular formula CrCl_(3).4 H_(2)O precipitates one mole of AgCl with AgNO_(3) solution. Its molar conductivity is found to be equivalent to two ions. What is the structural formula and name of the compound. |
|
Answer» Solution :Precipitation of ONE mole of AgCl shows that it has one ionizable Cl (outside the coordination SPHERE). Molar conductivity shows that one mole of the complex produces 2 moles of ions. Hence, the FORMULA is (keeping in mind that coordination number of Cr is 6). `[Cr(H_(2)O)_(4)Cl_(2)]^(+)Cl^(-)` NAME : tetraaquadichloridochromium (III) chloride. |
