ClO2 + H2O -> HClO2 + HClO3 — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Chlorine dioxide (ClO2) contains chlorine in an intermediate +4 oxidation state. It acts as a mixed anhydride. Step 2: Upon reacting with water, it disproportionates to form a mixture of chlorous acid (HClO2, +3 state) and chloric acid (HClO3, +5 state). Step 3: This yields two oxyacids: one with the "-ous" suffix (chlorous acid) and one with the "-ic" suffix (chloric acid), corresponding to option (c).
