Vedclass · Answer

(C) $1$. Identify the cation: $K^+$ is Potassium.$2$. Identify the ligand: $C_2O_4^{2-}$ is oxalate,and there are $3$ of them,so it is tris(oxalato).$3$. Identify the central metal atom: Since the complex ion $[Co(C_2O_4)_3]^{3-}$ is anionic,the metal $Co$ is named as cobaltate.$4$. Determine the oxidation state of $Co$: $x + 3(-2) = -3$,so $x = +3$.$5$. Combine the parts: Potassium tris(oxalato)cobaltate$(III)$.
