Correct answer: B. H2SO4
- A. HNO3
- B. H2SO4
- C. H2SO3
- D. H3PO4
Explanation
Sulfuric acid (H2SO4) is an acid that can act as an oxidizing, dehydrating, and acid-producing agent.Oxidizing agent: Sulfuric acid can act as an oxidizing agent under certain conditions. For example, in the presence of concentrated sulfuric acid, it can oxidize organic compounds containing reducing functional groups (e.g., alcohols) to form aldehydes, ketones, or carboxylic acids.Dehydrating agent: Sulfuric acid is a powerful dehydrating agent due to its strong affinity for water. When sulfuric acid reacts with water, it can remove water molecules from other compounds, leading to dehydration reactions. For example, when sulfuric acid reacts with sugar (C6H12O6), it removes water molecules to form carbon (as carbonaceous material) and water.Acid-producing agent: Sulfuric acid is a strong acid and can readily donate protons (H+) in aqueous solution, making it an effective acid-producing agent. In various chemical reactions, sulfuric acid can donate protons to other substances, leading to the formation of conjugate bases and resulting in acidic properties.

About Acids, Bases and Salts
Acid and base behaviour is explained through the Bronsted-Lowry transfer of protons and the Lewis donation or acceptance of electron pairs. The topic includes pH, pOH, ionisation and water equilibrium, plus salt formation and hydrolysis, where a salt solution may become acidic, basic or neutral.
