The correct order of the stoichiometries of AgCl formed when AgNO_{3} in excess is treated with the complexes: CoCl_{3} \cdot 6 NH_{3}, CoCl_{3} \cdot 5 NH_{3}, CoCl_{3} \cdot 4 NH_{3} respectively is:

Solution & Step-by-step Explanation

Stoichiometry of AgCl depends on the number of ionizable chloride ions outside the coordination sphere. CoCl_{3} \cdot 6 NH_{3} \to [Co (NH_{3})_{6}] Cl_{3} (3 ionizable Cl^{-}) \to 3 AgCl . CoCl_{3} \cdot 5 NH_{3} \to [Co (NH_{3})_{5} Cl] Cl_{2} (2 ionizable Cl^{-}) \to 2 AgCl . CoCl_{3} \cdot 4 NH_{3} \to [Co (NH_{3})_{4} Cl_{2}] Cl (1 ionizable Cl^{-}) \to 1 AgCl .Order: 3, 2, 1 .
