Vedclass · Answer

(A) $1$. The central metal ion is Cobalt in the $+3$ oxidation state,denoted as $Co(III)$.$2$. The ligand 'pentaammine' corresponds to $5$ ammonia molecules,$(NH_3)_5$.$3$. The ligand 'carbonato' corresponds to the carbonate ion,$CO_3^{2-}$.$4$. The coordination sphere is $[Co(NH_3)_5(CO_3)]$.$5$. To balance the charge: $Co$ is $+3$,$CO_3$ is $-2$,and $NH_3$ is $0$. The total charge on the coordination sphere is $(+3) + (-2) = +1$.$6$. To neutralize the $+1$ charge of the complex,one chloride ion $(Cl^-)$ is required outside the coordination sphere.$7$. Therefore,the correct formula is $[Co(NH_3)_5(CO_3)]Cl$.
