Answer the following questions with respect to the solutions marked 'A' and 'B' having pH values 4 and 10 respectively.
Which one of the two solutions will show acidic nature?

Answer

To determine which of the two solutions, A and B, shows acidic nature, we can follow these steps:

### Step-by-Step Solution:

1. **Understand pH Scale**: The pH scale ranges from 0 to 14. A pH value of less than 7 indicates an acidic solution, a pH of 7 indicates a neutral solution, and a pH greater than 7 indicates a basic (alkaline) solution.

2. **Identify the pH Values**:
- Solution A has a pH of 4.
- Solution B has a pH of 10.

3. **Analyze Solution A**: Since the pH of solution A is 4, which is less than 7, it indicates that solution A is acidic.

4. **Analyze Solution B**: The pH of solution B is 10, which is greater than 7. This indicates that solution B is basic.

5. **Conclusion**: Based on the pH values, solution A (pH 4) is acidic, while solution B (pH 10) is basic.

### Final Answer:
Solution A will show acidic nature.
