Product Overview
Bromocresol purple indicator solution is a highly reliable, synthetic pH-sensitive dye designed for precise acid-base titrations and pH monitoring in laboratory settings. This liquid indicator transitions sharply between yellow (acidic) and purple (basic) within the pH range of 5.2 to 6.8, ensuring accurate endpoint detection in titrations. Formulated with laboratory-grade purity, it delivers consistent results without interference from impurities, making it a trusted choice for analytical procedures. The solution is stable under standard lab conditions, with a long shelf life when stored properly in a cool, dark environment. Its water-soluble nature allows for seamless integration into aqueous solutions, while its non-toxic composition ensures safe handling with standard lab precautions. Whether used in volumetric analysis or routine pH testing, this indicator maintains its color intensity and responsiveness, reducing the need for frequent recalibration. The 125 ml pack size offers an optimal balance between cost-efficiency and practical usage volume, minimizing waste while ensuring sufficient supply for repeated experiments.
FAQs
1. What is the exact pH range where bromocresol purple changes color?
The color transition occurs between pH 5.2 (yellow) and pH 6.8 (purple), with a distinct intermediate green hue around the midpoint.
2. Can this indicator be used with non-aqueous solvents?
Bromocresol purple is primarily designed for aqueous solutions. For non-aqueous titrations, consider indicators like thymol blue or consult compatibility charts.
3. How should I store this solution to maintain its effectiveness?
Store the bottle tightly sealed in a cool, dark place away from direct sunlight and moisture to prevent degradation of the dye.
4. Is this indicator compatible with automated titration systems?
Yes, its stable color transition and lack of particulate matter make it suitable for both manual and automated titration setups.
5. What alternatives exist for detecting pH around 6.0?
Bromothymol blue (pH 6.0-7.6) or chlorophenol red (pH 5.2-6.8) can serve as alternatives depending on your specific pH range requirements.
