Ionisation isomerism

Vedclass · Answer

(C) The complex $A$ reacts with $AgNO_3$ to give a white precipitate,which indicates the presence of free $Cl^-$ ions outside the coordination sphere. Thus,$A$ is $[Co(NH_3)_5(SO_4)]Cl$.The complex $B$ reacts with $BaCl_2$ to give a white precipitate,which indicates the presence of free $SO_4^{2-}$ ions outside the coordination sphere. Thus,$B$ is $[Co(NH_3)_5Cl]SO_4$.Since the isomers differ in the ions they provide in solution,this is an example of Ionisation isomerism.
