ICl3 + H2O -> HIO2 + HCl — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Iodine trichloride (ICl3) features iodine in the +3 oxidation state. Step 2: During hydrolysis, the chlorine atoms are substituted by hydroxyl groups without changing the oxidation state of the iodine atom, producing iodous acid (HIO2) and hydrochloric acid (HCl). Step 3: Since the iodine-containing product is iodous acid, which carries the '-ous' suffix, the reaction belongs to category B.
