Which of the following metals produces hydrogen gas on reacting with cold dilute nitric acid?
- A \(\mathrm{Al}\)
- B \(\mathrm{Fe}\)
- C \(\mathrm{Mg}\)
- D \(\mathrm{Cu}\)
Answer & Solution
Correct Answer
(C) \(\mathrm{Mg}\)
Step-by-step Solution
Detailed explanation
Both magnesium \((\mathrm{Mg})\) and manganese \((\mathrm{Mn})\) react with very dilute cold \(\mathrm{HNO}_3\) to evolve \(\mathrm{H}_2\) gas. Magnesium metal reacts with dilute nitric acid to form magnesium nitrate and hydrogen gas…
