Vedclass · Answer

(C) The rules for naming a coordination compound are:$1.$ Name the counterion first: $Ammonium$.$2.$ Name the ligands in alphabetical order: $diaqua$ $(H_2O)$ and $oxalato$ $(C_2O_4^{2-})$. Since $oxalato$ is a polydentate ligand,we use $bis$ for the prefix.$3.$ Name the central metal atom: Since the complex is anionic,we add the suffix $-ate$ to $Nickel$,resulting in $nickelate$.$4.$ Determine the oxidation state of $Ni$: Let $x$ be the oxidation state of $Ni$. $2(+1) + x + 2(-2) + 2(0) = 0 \implies 2 + x - 4 = 0 \implies x = +2$.$5.$ Combine the parts: $Ammonium$ $diaquabis(oxalato)nickelate(II)$.
