Vedclass · Accepted Answer

$[CoCl_{3}(NH_{3})_{3}]$

Vedclass · Answer

(A) complex ionises in solution only if it has counter-ions outside the coordination sphere.In the complex $[CoCl_{3}(NH_{3})_{3}]$,all three $Cl^{-}$ ions are directly bonded to the central $Co^{3+}$ metal ion as ligands (satisfying both primary and secondary valencies).Since there are no ions outside the square brackets,it does not dissociate into ions in an aqueous solution.Therefore,it will not be precipitated by the addition of $AgNO_{3}$.
