Answer & Solution
Correct Answer
(D) \(\mathrm{Fe}_2 \mathrm{O}_3 \cdot x \mathrm{H}_2 \mathrm{O}\)
Step-by-step Solution
Detailed explanation
In the contact process for the manufacturer of sulfuric acid \(\left[\mathrm{H}_2 \mathrm{SO}_4\right]\) the arsenic purifier is crucial to remove arsenic impurities from the sulfur dioxide \(\left(\mathrm{SO}_2\right)\) gas before it enters the catalytic converter. The arsenic…
