Sample questions
-
1.Why is sulphur trioxide (SO₃) not directly dissolved in water to produce sulphuric acid?
- A.The reaction is endothermic and requires constant heating
- B.SO₃ forms a dense fog of acid particles and the reaction is highly exothermic
- C.Water reacts with SO₃ to form sulphurous acid instead of sulphuric acid
- D.SO₃ is insoluble in water and settles as a solid precipitate
-
2.When "sulphuric acid" is diluted with water, it behaves as an acid. Which of the following best explains this behavior?
- A.It ionizes completely into hydrogen ions (H⁺) and sulphate ions (SO₄²⁻), imparting acidic character.
- B.It decomposes into sulphur dioxide and water, releasing hydrogen gas.
- C.It reacts with water to form a basic solution due to hydroxide ion formation.
- D.It remains covalently bonded and does not release any ions in water.
-
3.A strong, non-volatile acid
- A.Sulphuric acid (H₂SO₄)
- B.Nitric Acid (HNO₃)
- C.Acetic Acid (CH₃COOH)
- D.Hydrochloric Acid (HCl)
-
4.What are the products formed when glucose ($$\mathrm{C_6H_{12}O_6}$$) is heated with concentrated sulphuric acid?
- A.$$6\mathrm{C} + 6\mathrm{H_2O}$$
- B.$$6\mathrm{CO_2} + 6\mathrm{H_2O}$$
- C.$$\mathrm{C_6H_{10}O_5} + \mathrm{H_2O}$$
- D.$$6\mathrm{CO} + 6\mathrm{H_2}$$
-
5.When using sulphuric acid to prepare other acids, which specific property of sulphuric acid is utilized?
- A.High solubility in water
- B.Strong oxidizing ability
- C.Least volatile acid
- D.High viscosity
