Oxidation state of in brown ring complex is: — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

In the brown ring complex, $NO$ exists as $NO^+$. <br>Calculation: $x + 5(0) + (+1) = +2$ (charge of complex ion). <br>$x + 1 = 2 \Rightarrow x = +1$. Iron is in the rare +1 oxidation state.
