Product Overview
Bromothymol Blue Indicator Solution (pH 6.3–6.5) is a highly sensitive, lab-grade reagent designed for accurate endpoint detection in acid-base titrations. This water-soluble indicator exhibits a distinct color transition from yellow (acidic) to blue (basic) within the narrow pH range of 6.3 to 6.5, ensuring sharp visual differentiation for precise analytical work. The solution is formulated to maintain stability under standard laboratory conditions, minimizing degradation over time. Its non-toxic composition and compatibility with aqueous systems make it a versatile choice for routine and specialized titration procedures. The 125 ml pack size provides sufficient volume for multiple experiments while maintaining cost efficiency. This indicator is free from interfering impurities, guaranteeing consistent performance across repeated applications. The solution’s balanced concentration ensures optimal color intensity without requiring additional dilution, streamlining workflow in laboratory settings.
FAQs
1. What is the exact pH range where Bromothymol Blue changes color?
The color transition occurs between pH 6.3 (yellow) and pH 6.5 (blue), with a green intermediate at the equivalence point.
2. Can this indicator be used in non-aqueous titrations?
Bromothymol Blue is primarily designed for aqueous systems and may exhibit altered behavior in organic solvents or non-polar media.
3. How should this solution be stored to maintain its shelf life?
Store in a tightly sealed amber glass bottle at room temperature, protected from direct sunlight and moisture to prevent degradation.
4. Is this indicator compatible with automated titration systems?
Yes, the solution’s consistent color intensity and rapid response make it suitable for both manual and automated titration setups.
5. What alternatives exist for titrations outside the 6.3–6.5 pH range?
For lower pH ranges, Methyl Orange (pH 3.1–4.4) or Phenolphthalein (pH 8.3–10.0) for higher ranges may be used depending on the application.
