FAQs
1. What is the pH range that this Universal Indicator covers?
This Universal Indicator is specifically formulated to cover a pH range from 4 to 11, providing distinct color changes within this spectrum to help identify the acidity or alkalinity of a solution.
2. How do I interpret the color changes of the indicator?
The indicator exhibits a range of colors: red for strong acids (pH 4), orange/yellow for weaker acids, green for neutral solutions (pH 7), blue for weaker bases, and purple for strong bases (pH 11).
3. Is this indicator suitable for use in titration experiments?
Yes, while primarily for general pH determination, its clear color transitions within the 4-11 range can be beneficial for monitoring progress in certain acid-base titrations, especially when a broad range indication is useful.
4. What are the recommended storage conditions for this solution?
For optimal shelf life and performance, store the Universal Indicator in a cool, dark place, away from direct sunlight and heat. Ensure the bottle is tightly sealed to prevent evaporation or contamination.
5. Can this Universal Indicator be used with turbid or colored samples?
Using the indicator with turbid or heavily colored samples can sometimes obscure the color changes, making accurate pH determination difficult. For such samples, alternative pH measurement methods might be more appropriate.
