Vedclass · Answer

(A) The complex $[Co(NH_3)_5SO_4]Cl$ can exist as two ionisation isomers: $[Co(NH_3)_5SO_4]Cl$ and $[Co(NH_3)_5Cl]SO_4$. Isomer $X$ reacts with $AgNO_3$ to give a white precipitate of $AgCl$,which indicates the presence of free $Cl^-$ ions in the coordination sphere. Thus,$X$ is $[Co(NH_3)_5SO_4]Cl$. Isomer $Y$ reacts with $BaCl_2$ to give a white precipitate of $BaSO_4$,which indicates the presence of free $SO_4^{2-}$ ions. Thus,$Y$ is $[Co(NH_3)_5Cl]SO_4$. Since these isomers differ in the exchange of ions between the coordination sphere and the counter-ion,they are ionisation isomers.

The octahedral complex $[Co(NH_3)_5SO_4]Cl$ exists in two isomeric forms $X$ and $Y$. Isomer $X$ reacts with $AgNO_3$ to give a white precipitate,but does not react with $BaCl_2$. Isomer $Y$ gives a white precipitate with $BaCl_2$ but does not react with $AgNO_3$. Isomers $X$ and $Y$ are $.....$
