Litmus Test and pH Value Interpretation
Litmus paper is a common indicator used to determine the acidic or basic nature of a solution.
- Blue litmus paper specifically turns red in the presence of an acidic substance.
- Conversely, red litmus paper turns blue in basic solutions, and neither changes color in neutral solutions.
Understanding Acidity and pH
The pH scale measures the concentration of hydrogen ions in a solution, determining its acidity or alkalinity.
- Solutions with a pH less than 7 are considered acidic.
- Solutions with a pH greater than 7 are considered alkaline or basic.
- A pH of exactly 7 indicates a neutral solution.
Conclusion from Litmus Test
Since the solution changes blue litmus paper to red, it indicates the presence of an acid. Therefore, the solution is acidic.
Based on the pH scale:
- Acidic solutions have a pH value less than 7.
Thus, the pH of this solution will be less than 7.
