Question

Sulphur(s) when react with HNO\(_3\) (conc.) Green mainly gives:

• A. \( \text{H}_2\text{SO}_4, \text{NO}_2 \) and \( \text{H}_2\text{O} \)
• B. \( \text{H}_2\text{S}, \text{N}_2\text{O}_5 \) and \( \text{SO}_2 \)
• C. \( \text{H}_2\text{SO}_3, \text{NO}_2 \) and \( \text{SO}_2 \)
• D. \( \text{SO}_2, \text{NO}_2 \) and \( \text{H}_2\text{O} \)

Hint:

The reaction between sulphur and concentrated nitric acid leads to the formation of sulfuric acid and nitrogen oxides, including NO\(_2\).

Answer 1

The Correct Option is A

When sulphur reacts with concentrated nitric acid (HNO\(_3\)), it undergoes oxidation to produce sulfuric acid (\( \text{H}_2\text{SO}_4 \)), nitrogen dioxide (\( \text{NO}_2 \)) and water (\( \text{H}_2\text{O} \)) as the products.
The reaction can be represented as follows: \[ \text{S} + 2 \text{HNO}_3 \to \text{H}_2\text{SO}_4 + \text{NO}_2 + \text{H}_2\text{O} \]
Thus, the correct answer is (a).
