Sample questions
-
1.Which of the following percentages correctly represents the concentration of nitric acid by weight in constant boiling nitric acid?
- A.50% HNO₃ by weight
- B.68% HNO₃ by weight
- C.80% HNO₃ by weight
- D.98% HNO₃ by weight
-
2.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
-
3.Which solution produces nitrogen dioxide when reacted with copper?
- A.Dilute hydrochloric acid
- B.Concentrated nitric acid
- C.Dilute sulphuric acid
- D.Sodium hydroxide solution
-

- D.Assertion is false, but reason is true.
-
5.What observation is made when lead nitrate is heated strongly in a test tube?
- A.A white precipitate forms with no gas evolution
- B.Yellow lead oxide forms with dense brown fumes of nitrogen dioxide
- C.A colorless gas is released with no color change
- D.The powder turns black with white fumes
