Q. The correct order of the stoichiometries of AgCl formed when $AgNO_3$ in excess is treated with the complexes : $CoCl_3.6NH_3$, $CoCl_3.5NH_3$, $CoCl_3.4NH_3$ respectively is :
A) 1 AgCl, 3 AgCl, 2 AgCl
B) 3 AgCl, 1 AgCl, 2 AgCl
C) 3 AgCl, 2 AgCl, 1 AgCl
D) 2 AgCl, 3 AgCl, 1 AgCl
Explanation
[Solution] $[Co(NH_3)_6]Cl_3$, $[Co(NH_3)_5Cl]Cl_2$ and $[Co(NH_3)_4Cl_2]Cl$ have 3, 2 and 1 ionisable chlorides. Answer (3).
