Product Overview
Bromothymol blue indicator powder is a highly sensitive pH indicator widely used in laboratories for accurate acid-base titrations and colorimetric analysis. This lab-grade powder transitions from yellow in acidic solutions (pH 7.6), with a distinct green intermediate at neutral pH (6.0–7.6). Its fine particle size ensures rapid dissolution and uniform color development, making it ideal for precise endpoint detection in volumetric analysis. The indicator is chemically stable under standard storage conditions, ensuring long-term reliability for repeated use. Compatible with aqueous and alcoholic solvents, it maintains consistent performance across diverse experimental setups. Free from impurities, this bromothymol blue variant guarantees minimal interference with test results, delivering dependable color changes even at low concentrations. Whether used in educational demonstrations or research applications, its high purity and sharp color contrast enhance experimental accuracy and reproducibility.
FAQs
1. What is the pH range for bromothymol blue indicator powder?
Bromothymol blue transitions from yellow (pH 7.6), with a green intermediate at neutral pH (6.0–7.6).
2. Can this indicator be used in non-aqueous solvents?
Yes, bromothymol blue is soluble in alcoholic solvents like ethanol, though its color intensity may vary slightly compared to aqueous solutions.
3. How should bromothymol blue powder be stored for long-term use?
Store in a tightly sealed container, protected from light and moisture, at room temperature (15–25°C) to maintain stability.
4. Is this indicator compatible with strong oxidizing agents?
No, bromothymol blue may degrade or discolor when exposed to strong oxidizers like chlorine or hydrogen peroxide.
5. What alternatives exist for pH indicators with a similar range?
Alternatives include phenol red (pH 6.8–8.4) or thymol blue (pH 8.0–9.6), though their transition colors differ.
