Vedclass · Answer

(B) $1$. Identify the cation: $Na^+$ is sodium.$2$. Identify the coordination entity: $[Co(ONO)_6]^{3-}$.$3$. The ligand is $ONO^-$,which is named 'nitrito-$O$'. Since there are $6$ such ligands,it is 'hexanitrito-$O$'.$4$. The central metal is cobalt. Since the complex ion is anionic,it is named 'cobaltate'.$5$. Calculate the oxidation state of $Co$: $x + 6(-1) = -3$,so $x = +3$.$6$. Combining these,the name is Sodium hexanitrito-$O$-cobaltate$(III)$.
