H2SO5 + H2O -> H2SO4 + H2O2 — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Peroxomonosulfuric acid (H2SO5, also known as Caro's acid) contains sulfur in the +6 oxidation state. Step 2: Hydrolysis splits the peroxy linkage, yielding sulfuric acid (H2SO4) and hydrogen peroxide (H2O2) while the oxidation state of the sulfur remains unchanged. Step 3: The sulfur-containing product, sulfuric acid, possesses the '-ic' suffix, which places this reaction in category A.
