Question
In a closed container there is a mixture of SO2, CO2 and O2 gas. Which sequence of reagent can be helpful to separate them? (I) Limewater (II) Acidified potassium dichromate (III) Alkaline pyragallol.
Answer: B
💡 Solution & Explanation
Step 1: Pyrophosphoric acid (H4P2O7) contains phosphorus in the +5 oxidation state. It undergoes hydrolysis to yield orthophosphoric acid (H3PO4). 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).
