Q. Which complex cannot ionize in solution?
A) $\lbrack{CoCl}_{3}\left( {NH}_{3} \right)_{3}\rbrack$
B) $K_{4}(Fe(CN)_{6}\rbrack$
C) $K_{2}\lbrack Pt(F_{6})\rbrack$
D) $\left\lbrack Pt\left( {NH}_{3} \right)_{6} \right\rbrack{Cl}_{4}$
Explanation
(a)
$\lbrack{CoCl}_{3}\left( {NH}_{3} \right)_{3}\rbrack$ cannot ionize in solution because three chloride ions satisfy primary and secondary valencies. It will not be precipitated by the addition of${AgNO}_{3}$.
