Magnesium on reaction with (very dilute) HNO3 gives:
Correct answer: C. H2
- A. NO
- B. N2O
- C. H2
- D. NO2
Explanation
When magnesium reacts with very dilute nitric acid, it forms magnesium nitrate and hydrogen gas is evolved. The nitric acid being very dilute acts as a weak oxidizing agent, unable to oxidize the hydrogen gas. Therefore, the correct answer is Option C: H2.Option A: NO, Option B: N2O, and Option D: NO2 are incorrect because they are not the products formed when magnesium reacts with very dilute nitric acid.
