Sample questions
-
1.Which balanced equation correctly shows the reaction of copper with concentrated nitric acid upon heating?
- A.Cu + 4HNO₃ → Cu(NO₃)₂ + 2H₂O + 2NO₂↑
- B.Cu + HNO₃ → Cu(NO₃)₂ + H₂O + NO↑
- C.Cu + 2HNO₃ → Cu(NO₃)₂ + H₂↑
- D.Cu + 6HNO₃ → Cu(NO₃)₂ + 3H₂O + 3NO₂↑
-
2.Write the balanced chemical equation for the reaction of concentrated nitric acid with carbon. What is the role of nitric acid in this reaction?
- A.It acts as a reducing agent, converting carbon to carbon dioxide.
- B.It acts as an oxidising agent, providing nascent oxygen to oxidise carbon to carbon dioxide.
- C.It acts as a catalyst, speeding up the reaction without being consumed.
- D.It acts as a dehydrating agent, removing water from the reaction mixture.
-
3.Which acid does not evolve H₂ gas with metals?
- A.H₂SO₄
- B.HNO₃
- C.HCl
- D.All of these
-
4.What change is observed when nitric acid is kept in a reagent bottle for a long time?
- A.It turns brown in color
- B.It turns colorless
- C.It forms a white precipitate
- D.It solidifies into crystals
-
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
