H3PO5 + H2O -> H3PO4 + H2O2 — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Peroxomonophosphoric acid (H3PO5) contains a peroxy linkage (-O-O-) with phosphorus in the stable +5 oxidation state. Step 2: Hydrolysis cleaves the weak peroxy bond, forming orthophosphoric acid (H3PO4) and hydrogen peroxide (H2O2) while preserving the +5 state on the phosphorus atom. Step 3: The primary phosphorus-containing product is phosphoric acid, which has the '-ic' suffix, placing this reaction in category A.
