Which of the following chloride does not react with PCl5 on heating? — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Peroxodiphosphoric acid (H4P2O8) contains phosphorus in the +5 oxidation state with a peroxy linkage. Hydrolysis of H4P2O8 yields orthophosphoric acid (H3PO4) and hydrogen peroxide (H2O2). Step 2: Orthophosphoric acid has the "-ic" suffix. Step 3: Therefore, the phosphorus-containing product is an oxyacid with an "-ic" suffix, matching option (a).
