Vedclass · Answer

(A) The charge on a coordination complex is the sum of the oxidation states of the central metal atom and the charges on the ligands.For $[Co(NH_3)_3Cl_3]$:$Co$ is in the $+3$ oxidation state.$NH_3$ is a neutral ligand (charge $= 0$).$Cl^-$ is an anionic ligand (charge $= -1$).Total charge $= (+3) + 3(0) + 3(-1) = +3 + 0 - 3 = 0$.Since the total charge is $0$,the complex is neutral.

The complex $[Co(NH_3)_3Cl_3]$ is ............ .
