An octahedral complex is prepared by mixing CoCl_3 and NH_3 in the molar ratio of 1 : 4 . 0.1 m solutioin of this complex was found to freeze at -0.372^(@) C. What is the formula of the complex ? Given the molal depression content (K_f) for water = 1.86^(@) cm |

Answer» Solution :Theoretical value of `deltaT_f` can be calculates as : Observed value is twice the theoretical value, this means that each MOLECULE of the COMPLEX dissociation is give two IONS. This can be possible in case the complexes has the FORMULA `[Co(NH_3)_(4)Cl_2]Cl` . |
