N2O3 + H2O -> HNO2 — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Dinitrogen trioxide (N2O3) is the anhydride of nitrous acid (HNO2), with nitrogen in the +3 oxidation state. Step 2: Hydrolysis of N2O3 yields nitrous acid (HNO2). Nitrous acid has the "-ous" suffix. Step 3: Since the nitrogen-containing product is an oxyacid with a "-ous" suffix, the correct option is (b).
