Vedclass · Answer

(D) $1$. Identify the cation: The cation is $K^+$,which is named as Potassium. The number of potassium ions is not mentioned in the $IUPAC$ name.$2$. Identify the ligand: The ligand is $ox^{2-}$ (oxalate ion). Since there are $3$ oxalate ligands,the prefix is 'tri'. The ligand name becomes 'trioxalato'.$3$. Identify the central metal atom: The complex ion is $[Co(ox)_3]^{3-}$. Since the complex ion is anionic,the metal $Co$ is named as 'cobaltate'.$4$. Determine the oxidation state: Let the oxidation state of $Co$ be $x$. The charge on oxalate is $-2$. So,$x + 3(-2) = -3$,which gives $x - 6 = -3$,so $x = +3$. The oxidation state is written in Roman numerals in parentheses: $(III)$.$5$. Combine the parts: The name is Potassium trioxalatocobaltate $(III)$.

The $IUPAC$ name of the complex shown below is $K_3[Co(ox)_3]$
