Vedclass · Answer

(C) The reaction with $AgNO_3$ depends on the presence of ionizable halide ions outside the coordination sphere.$AgBr$ is a pale yellow precipitate,and $AgCl$ is a white precipitate.In option $C$,the first complex is $[Pt(NH_3)_4Cl_2]Br_2$,which ionizes to give $2Br^-$ ions. These react with $Ag^+$ to form $AgBr$ (pale yellow precipitate).The second complex is $[Pt(NH_3)_4Br_2]Cl_2$,which ionizes to give $2Cl^-$ ions. These react with $Ag^+$ to form $AgCl$ (white precipitate).Therefore,the pair in option $C$ satisfies the condition.

Which of the following pairs of complexes gives pale yellow and white precipitates respectively when their aqueous solutions are treated with $0.1 \ M \ AgNO_3$?
