The correct Answer is:
To determine the nature of `Al2O3` (aluminum oxide) and `B2O3` (boron oxide), we need to analyze their chemical properties and how they react with acids and bases. ### Step 1: Analyze `B2O3` - **Nature of `B2O3`**: - `B2O3` is known as boron trioxide. - When `B2O3` reacts with water, it forms boric acid (`H3BO3`). - The formation of an acid indicates that `B2O3` behaves as an acidic oxide. ### Step 2: Analyze `Al2O3` - **Nature of `Al2O3`**: - `Al2O3` is known as aluminum oxide. - It exhibits amphoteric behavior, meaning it can react with both acids and bases. - For example: - When `Al2O3` reacts with hydrochloric acid (`HCl`), it forms aluminum chloride (`AlCl3`) and water. - When `Al2O3` reacts with sodium hydroxide (`NaOH`), it forms sodium aluminate (`NaAlO2`) and water. - This dual reactivity (with both acids and bases) confirms that `Al2O3` is amphoteric. ### Conclusion - The nature of `B2O3` is **acidic**. - The nature of `Al2O3` is **amphoteric**. ### Final Answer - `B2O3` is acidic, and `Al2O3` is amphoteric. ---
