The correct Answer is:
To determine which of the given substances will behave as a basic solution when dissolved in water, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Substances**: The question mentions a 0.1 M solution of various substances. We need to identify the substances provided in the question. Let's assume the substances are: - Sodium Borate (Na2B4O7) - Calcium Nitrate (Ca(NO3)2) - Ammonium Chloride (NH4Cl) - Sodium Sulfate (Na2SO4) 2. **Understand the Concept of Basicity**: A solution behaves basic if it contains a salt derived from a strong base and a weak acid. In contrast, a salt from a strong acid and a weak base will produce an acidic solution. 3. **Analyze Each Substance**: - **Sodium Borate (Na2B4O7)**: This salt is derived from sodium hydroxide (a strong base) and boric acid (a weak acid). Therefore, it will behave basic in solution. - **Calcium Nitrate (Ca(NO3)2)**: This salt is derived from calcium carbonate (a weak base) and nitric acid (a strong acid). Hence, it will not behave basic; it will be neutral or slightly acidic. - **Ammonium Chloride (NH4Cl)**: This salt is derived from ammonium hydroxide (a weak base) and hydrochloric acid (a strong acid). It will behave acidic in solution. - **Sodium Sulfate (Na2SO4)**: This salt is derived from sodium hydroxide (a strong base) and sulfuric acid (a strong acid). It will also be neutral or slightly acidic. 4. **Conclusion**: Among the substances analyzed, only Sodium Borate (Na2B4O7) will behave basic in a 0.1 M solution. ### Final Answer: The 0.1 M solution of **Sodium Borate (Na2B4O7)** will behave basic.
