Product Overview
Phenolphthalein solution is a widely used pH indicator in laboratories, known for its sharp color transition from colorless to pink in alkaline environments. This solution is essential for acid-base titrations, providing clear visual endpoints for precise measurements. The laboratory-grade formulation ensures reliability and consistency in experimental results. Phenolphthalein is non-toxic and safe for standard lab use, making it a staple in educational and research settings. Its stability and sensitivity to pH changes make it a preferred choice for qualitative and quantitative chemical analysis. The solution is compatible with most standard lab equipment and can be stored at room temperature for extended periods without degradation.
FAQs
1. What is the shelf life of phenolphthalein solution?
The solution remains stable for up to 2 years when stored properly in a cool, dry place away from direct sunlight.
2. Can this solution be used for industrial applications?
While primarily designed for laboratory use, it can be adapted for industrial pH testing with proper calibration.
3. Is phenolphthalein solution compatible with plastic containers?
Yes, it can be stored in high-density polyethylene (HDPE) or glass containers to prevent contamination.
4. What alternatives are available if phenolphthalein is unavailable?
Methyl orange or bromothymol blue can be used as substitutes, though they have different pH ranges.
5. How should I dispose of expired phenolphthalein solution?
Follow local laboratory waste disposal guidelines, as it is generally non-hazardous but should not be poured down drains.
