Vedclass · Answer

(A) In coordination compounds,the species present inside the square brackets $[...]$ is the coordination sphere and does not ionize in an aqueous solution. Only the species present outside the coordination sphere (counter ions) ionize. For $[Co(NH_3)_3Cl_3]$,there are no counter ions outside the coordination sphere,so it is non-ionizable. For the other options: $B$: $[Co(NH_3)_4Cl_2]Cl$ gives $Cl^-$ ions. $C$: $[Co(NH_3)_5Cl]Cl_2$ gives $2Cl^-$ ions. $D$: $[Co(NH_3)_6]Cl_3$ gives $3Cl^-$ ions. Therefore,the correct option is $A$.
