Trioxalatochromate$(III)$ ion

Vedclass · Answer

(B) $1$. The complex ion is $[Cr(C_2O_4)_3]^{3-}$.$2$. The ligand is oxalate $(C_2O_4^{2-})$,which is an anionic ligand,so the suffix '-ate' is added to the metal name.$3$. There are three oxalate ligands,so the prefix 'tri' is used.$4$. The oxidation state of $Cr$ is calculated as: $x + 3(-2) = -3$,which gives $x = +3$.$5$. Combining these,the name is trioxalatochromate$(III)$ ion.
