The molar conductivity of the complex CoCl ₃ 4 NH ₃ 2 H ₂ O is found to be the same as that of a 1: 3 electrolyte. The structural formula of the compound is :

Step-by-step solution

The molar conductivity of a 1:3 electrolyte indicates that the complex dissociates into 4 ions in total, consisting of one complex cation and three chloride anions. This implies that all three chloride ions are present outside the coordination sphere as counter ions. The coordination number of Cobalt in such complexes is typically 6 . The formula given is CoCl ₃ 4 NH ₃ 2 H ₂ O . If the complex is a 1:3 electrolyte, the structure must be of the form [ Co ( NH ₃)₄( H ₂ O )₂] Cl ₃ . In this structure, the coordination
