Vedclass · Answer

(B) complex is cationic if the coordination sphere carries a positive charge.$Na_4[Fe(CN)_6]$ dissociates into $4Na^+$ and $[Fe(CN)_6]^{4-}$,which is an anionic complex.$[Co(NH_3)_5Cl]SO_4$ dissociates into $[Co(NH_3)_5Cl]^{2+}$ and $SO_4^{2-}$,which is a cationic complex.$[Ni(CO)_4]$ is a neutral complex as it has no charge.$K_3[Fe(CN)_6]$ dissociates into $3K^+$ and $[Fe(CN)_6]^{3-}$,which is an anionic complex.Therefore,the correct option is $B$.
