Product Overview
Bromocresol green 0.1% w/v aqueous solution is a highly reliable pH indicator designed for laboratory applications requiring precise acid-base detection. This water-soluble dye exhibits a distinct color transition from yellow (acidic) to blue (basic) within the pH range of 3.8 to 5.4, making it indispensable for titrations, buffer preparations, and qualitative analysis. Formulated as a ready-to-use solution, it eliminates the need for dilution, ensuring consistency and accuracy in experimental workflows. The reagent-grade purity guarantees minimal interference, while its stable aqueous formulation extends shelf life without compromising performance. Ideal for educational labs, research settings, or industrial quality control, this solution adheres to stringent manufacturing standards to deliver reproducible results. Store in a cool, dark place to preserve its sensitivity and avoid contamination from direct light or moisture.
FAQs
1. What is the exact pH range where bromocresol green changes color?
The color transition occurs between pH 3.8 (yellow) and 5.4 (blue), with a green intermediate at neutral pH.
2. Can this solution be used for microbial growth media?
No, bromocresol green is not suitable for microbial culture media as it may inhibit growth or interfere with metabolic indicators.
3. How should I dispose of unused bromocresol green solution?
Follow local chemical waste disposal guidelines; neutralize with a compatible base/acid if required before disposal.
4. Is this solution compatible with organic solvents?
It is primarily designed for aqueous systems; solubility in organic solvents like ethanol may vary and could alter its indicator properties.
5. What alternatives exist for broader pH range testing?
For wider ranges, consider universal indicators or combinations like methyl red and phenolphthalein for multi-range detection.
