Vedclass · Answer

(D) The formation of an $AgCl$ precipitate with $AgNO_3$ indicates that the $Cl^-$ ion is present in the ionization sphere (outside the coordination sphere).The absence of an $AgBr$ precipitate indicates that the $Br^-$ ions are present inside the coordination sphere.Conductance measurements showing two ions per formula unit confirm that the complex dissociates into two ions: $[CoBr_2(NH_3)_4]^+$ and $Cl^-$.Therefore,the structural formula is $[CoBr_2(NH_3)_4]Cl$.The reaction is: $[CoBr_2(NH_3)_4]Cl + AgNO_3 \rightarrow [CoBr_2(NH_3)_4]NO_3 + AgCl(s)$.

$A$ complex has a composition corresponding to the formula $CoBr_2Cl \cdot 4NH_3$. What is the structural formula if conductance measurements show two ions per formula unit? Silver nitrate solution gives an immediate precipitate of $AgCl$ but no $AgBr$.
