Sample questions
-
1.Which of the following represents the balanced chemical equation for the reaction of hot and concentrated nitric acid on copper?
- A.Cu + 2HNO₃ (hot & conc.) → Cu(NO₃)₂ + H₂O + NO₂
- B.Cu + 4HNO₃ (hot & conc.) → Cu(NO₃)₂ + 2H₂O + 2NO₂
- C.3Cu + 8HNO₃ (hot & conc.) → 3Cu(NO₃)₂ + 4H₂O + 2NO
- D.Cu + HNO₃ (hot & conc.) → CuNO₃ + H₂O + NO
-
2.A dilute acid B does not normally give hydrogen when reacted with metals but does give a gas when it reacts with copper. Identify the acid B and select the correct option regarding its reaction with copper.
- A.B is dilute hydrochloric acid. Equation: Cu + 2HCl → CuCl₂ + H₂.
- B.B is dilute nitric acid. Equation: 3Cu + 8HNO₃ → 3Cu(NO₃)₂ + 2NO + 4H₂O.
- C.B is dilute sulphuric acid. Equation: Cu + H₂SO₄ → CuSO₄ + H₂.
- D.B is carbonic acid. Equation: Cu + H₂CO₃ → CuCO₃ + H₂.

3.In the preparation of nitric acid by heating suitable reactants, what type of salt is formed as an intermediate product?
- A.Basic salt
- B.Acid salt
- C.Normal salt
- D.Double salt
-
4.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
-
5.Which balanced chemical equation represents the reaction of sulphur with hot concentrated nitric acid?
- A.S + 4HNO₃ → H₂SO₄ + 4NO₂ + 2H₂O
- B.S + 6HNO₃ → H₂SO₄ + 6NO₂ + 2H₂O
- C.S + 2HNO₃ → H₂SO₄ + 2NO
- D.S + HNO₃ → H₂SO₄ + NO₂ + H₂O
