**(A):** The oxidation state of Iron in the brown ring complex is +1. <br> **(R):** In this complex, — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

**Assertion:** Experimental evidence (magnetic moment) confirms Fe is in +1 state. True. <br>**Reason:** $NO$ acts as a $1e^-$ donor to $Fe^{2+}$, reducing it to $Fe^+$ and becoming $NO^+$. True and explains the calculation $(x + 0 + 1 = 2 \Rightarrow x=1)$.
