Q. The complex that doesn’t give a precipitate with ${AgNO}_{3}$solution
A) $\lbrack Co\left( {NH}_{3} \right)_{3}3{Cl}_{3}\rbrack$
B) $\left\lbrack Co\left( {NH}_{3} \right)_{6} \right\rbrack{Cl}_{3}$
C) $\lbrack Ag\left( {NH}_{3} \right)_{2}\rbrack Cl$
D) $\lbrack Cr\left( {NH}_{3} \right)_{4}{Cl}_{2}\rbrack Cl$
Explanation
(a)
$\lbrack Co\left( {NH}_{3} \right)_{3}{Cl}_{3}\rbrack$ does not give a precipitate with ${AgNO}_{3}$solution because all the chloride ions are non-ionizable.
$\lbrack Co\left( {NH}_{3} \right)_{3}{Cl}_{3}\rbrack \rightleftharpoons$does not ionise
