Question:
In the contact process of manufacturing \(\text{H}_2\text{SO}_4\), the arsenic purifier used in the industrial plant contains:
In the contact process of manufacturing \(\text{H}_2\text{SO}_4\), the arsenic purifier used in the industrial plant contains:
Show Hint
Arsenic impurities in the sulfur dioxide feed are removed using hydrated iron oxide in the contact process.
- Ferric oxide acts as an adsorbent for arsenic compounds, preventing catalyst poisoning in the reaction.

The Correct Option is D
Solution and Explanation
Step 1: Role of Arsenic Purifiers in the Contact Process
- The contact process for producing \(\text{H}_2\text{SO}_4\) requires removing impurities such as arsenic from sulfur dioxide (\(\text{SO}_2\)).
- \(\text{Fe}_2\text{O}_3\) (ferric oxide) in hydrated form (\(\text{Fe}_2\text{O}_3 \cdot x\text{H}_2\text{O}\)) is used to absorb and purify arsenic.
Hence, the correct answer is \(\text{Fe}_2\text{O}_3 \cdot x\text{H}_2\text{O}\).
