The Correct Option is D
Solution and Explanation
Step 1: Write the coordination formula.
CoCl\(_3\)\(\cdot\)3NH\(_3\) corresponds to \([\mathrm{Co(NH_3)_3Cl_3}]\).
Step 2: Analyze ionization.
All chloride ions are inside the coordination sphere.
No ions are present outside the coordination sphere.
Step 3: Conductance and AgNO\(_3\) test.
No free ions in solution ⇒ molar conductance is zero.
No Cl\(^{-}\) ions are precipitated by AgNO\(_3\).
Step 4: Conclusion.
Molar conductance = 0 and number of Cl\(^{-}\) ions precipitated = 0.
CoCl\(_3\)\(\cdot\)3NH\(_3\) corresponds to \([\mathrm{Co(NH_3)_3Cl_3}]\).
