Type: MCQ-conceptual-Medium-Class 12
The CORRECT order of the stoichiometries of AgCl formed when AgNO₃ in excess is treated with the complex: CoCl₃.6NH₃, CoCl₃.5NH₃, CoCl₃.4NH₃, respectively is ________.
A
3 AgCl, 1 AgCl, 2 AgCl
B
2 AgCl, 3 AgCl, 1 AgCl
C
3 AgCl, 2 AgCl, 1 AgCl
D
1 AgCl, 3 AgCl, 2 AgCl
Correct Answer
Option C
Detailed Explanation
The number of chloride ions available for precipitation as AgCl depends on the number of NH₃ ligands. More NH₃ ligands mean fewer chloride ions are free to react with AgNO₃.
