H2S2O6 + H2O -> H2SO3 + H2SO4 — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Dithionic acid (H2S2O6) has sulfur in an intermediate average oxidation state of +5. Step 2: Hydrolysis of dithionic acid breaks the S-S bond and yields a mixture of sulfurous acid (H2SO3, +4 state) and sulfuric acid (H2SO4, +6 state). Step 3: Since this yields two different sulfur oxyacids—one with a '-ous' suffix and the other with an '-ic' suffix—it corresponds to category C.
