Sample questions
-
1.Which metal nitrate decomposes on heating to form the metal itself?
- A.Copper nitrate (Cu(NO₃)₂)
- B.Sodium nitrate (NaNO₃)
- C.Silver nitrate (AgNO₃)
- D.Lead nitrate (Pb(NO₃)₂)
-
2.During a thunderstorm, the rain water contains Nitric acid. The Nitric acid is formed as a result of three chemical reactions. Which of the following sets of balanced chemical equations correctly represents these three reactions?
- A.1. N₂ + O₂ → 2NO 2. 2NO + O₂ → 2NO₂ 3. 4NO₂ + 2H₂O + O₂ → 4HNO₃
- B.1. N₂ + 2O₂ → 2NO₂ 2. 2NO₂ + H₂O → HNO₃ + HNO₂ 3. 2HNO₂ + O₂ → 2HNO₃
- C.1. N₂ + O₂ → NO₂ 2. NO₂ + H₂O → HNO₃ 3. 2HNO₃ + O₂ → 2HNO₄
- D.1. N₂ + 3O₂ → 2NO₃ 2. 2NO₃ + H₂O → 2HNO₃ 3. HNO₃ + O₂ → HNO₄
-
3.A nitrate which forms a precipitate with ammonium hydroxide and is also soluble in excess of it:
- a.ferrous nitrate
- b.ferric nitrate
- c.lead nitrate
- d.copper nitrate
-
4.Assertion : Nitric acid can be used to oxidize non-metals such as carbon and sulfur. Reason : Nitric acid reacts with non-metals to form their respective oxides and nitrogen dioxide. (a) Both assertion and reason are true and reason is the correct explanation of assertion. (b) Both assertion and reason are true, but reason is not the correct explanation of assertion. (c) Assertion is true, but reason is false. (d) Assertion is false, but reason is true.
- A.Both assertion and reason are true and reason is the correct explanation of assertion.
- B.Both assertion and reason are true, but reason is not the correct explanation of assertion.
- C.Assertion is true, but reason is false.
- D.Assertion is false, but reason is true.

5.Copper on reduction with dilute HNO₃ produces a gas 'X'. This gas on reduction with SnCl₂/HCl forms 'Y', which on further oxidations gives Z. Identify X, Y, Z
- A.X = NO, Y = NH₂OH, Z = N₂O
- B.X = NO, Y = NH₂OH.HCl, Z = N₂O
- C.X = NO₂, Y = NH₂OH, Z = N₂O
- D.X = NO, Y = NH₂OH.HCl, Z = NO₂
