Sodium nitroprusside is an important coordination complex used in qualitative inorganic analysis. Wh — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

The formula of sodium nitroprusside is $Na_2[Fe(CN)_5NO]$ , resulting in a complex ion of $[Fe(CN)_5NO]^{2-}$ . The unique nitrosonium ligand ( $NO$ ) is present as an exotic $NO^+$ cation, and the five cyanide ligands are $CN^-$ . Let $x$ be the apparent oxidation state of Fe. Applying algebraic rules: $x + 5(-1) + 1(+1) = -2 \Rightarrow x - 4 = -2 \Rightarrow x = +2$ .
