Sample questions
-
1.(v) Commercial sample of Nitric acid is pale yellow in colour due to the presence of dissolved
- A.Sulphur
- B.Sulphuric acid
- C.Oxygen
- D.Nitrogen dioxide
-
2.What happens when dilute nitric acid reacts with magnesium, and which balanced chemical equation represents this reaction?
- A.Magnesium reacts with dilute nitric acid to liberate hydrogen gas: Mg + 2HNO₃ (dil.) → Mg(NO₃)₂ + H₂
- B.Magnesium reacts with dilute nitric acid to produce nitrogen dioxide gas: Mg + 4HNO₃ → Mg(NO₃)₂ + 2NO₂ + 2H₂O
- C.Magnesium does not react with dilute nitric acid and remains inert.
- D.Magnesium reacts with dilute nitric acid to form ammonia: Mg + HNO₃ → Mg(NO₃)₂ + NH₃
-
3.Write the balanced chemical equation for the reaction of concentrated nitric acid with copper. Which gas is evolved in this reaction?
- A.Nitrogen monoxide (NO)
- B.Nitrogen dioxide (NO₂)
- C.Dinitrogen tetroxide (N₂O₄)
- D.Ammonia (NH₃)
-
4.Cold, dilute nitric acid reacts with copper to form _______
- A.Hydrogen
- B.Nitrogen dioxide
- C.Nitric oxide
-
5.Which statement correctly describes the acidic behavior of nitric acid with metallic oxides and hydroxides, along with the correct balanced equations for each reaction?
- A.Nitric acid reacts with metallic oxides and hydroxides to form salt and water. CuO + 2HNO₃ → Cu(NO₃)₂ + H₂O; NaOH + HNO₃ → NaNO₃ + H₂O
- B.Nitric acid reacts with metallic oxides and hydroxides to form salt and hydrogen gas. CuO + HNO₃ → Cu(NO₃) + H₂; NaOH + HNO₃ → NaNO₃ + H₂
- C.Nitric acid reacts with metallic oxides and hydroxides to form salt, water, and nitrogen dioxide. CuO + 4HNO₃ → Cu(NO₃)₂ + 2H₂O + 2NO₂; NaOH + 2HNO₃ → NaNO₃ + H₂O + NO₂
- D.Nitric acid reacts with metallic oxides and hydroxides to form metallic nitrates only. CuO + HNO₃ → CuNO₃; NaOH + HNO₃ → NaNO₃
