Sagot :

To determine which pH represents a neutral solution, we need to understand the pH scale.

The pH scale ranges from 0 to 14 and measures how acidic or basic a solution is:
- A pH less than 7 indicates an acidic solution.
- A pH greater than 7 indicates a basic (alkaline) solution.
- A pH exactly equal to 7 indicates a neutral solution.

Given the options:
1. 1.25: This is less than 7, indicating an acidic solution.
2. 5.40: This is also less than 7, so it represents an acidic solution.
3. 8.65: This is greater than 7, so it indicates a basic solution.
4. 7.00: This is exactly equal to 7, which represents a neutral solution.

Therefore, the pH that represents a neutral solution is 7.00.
