Statements:
A) H$_2$SO$_4$ is used in the refining of petroleum to remove sulphur and other compounds.
B) The basic nature of Sodium Hydroxide (NaOH) is due to the presence of Hydrogen ions in the solution.
Statement A Analysis: Petroleum Refining with H2SO4
Statement A claims that sulfuric acid (H2SO4) is used in petroleum refining to remove sulfur and other compounds. This is true. Sulfuric acid is employed in petroleum refining processes, such as acid treating, to remove impurities like sulfur compounds, nitrogen compounds, and unsaturated hydrocarbons (olefins). It reacts with these impurities, forming sludge that is subsequently removed.
Statement B Analysis: Basic Nature of Sodium Hydroxide (NaOH)
Statement B asserts that the basic nature of Sodium Hydroxide (NaOH) is due to the presence of Hydrogen ions (H+) in solution. This is false.
- Sodium Hydroxide (NaOH) is a strong base.
- Its basic nature arises from the dissociation in water to produce Sodium ions (Na+) and Hydroxide ions (OH-).
- The presence of Hydroxide ions (OH-) in solution makes a substance basic, as these ions can accept protons (H+).
- Conversely, the presence of Hydrogen ions (H+) typically indicates an acidic nature.
Conclusion: Evaluating Statements A and B
Based on the analysis:
- Statement A is true.
- Statement B is false.
Therefore, the correct option is the one stating that only statement A is true.
