pH 8.8 (colorless) - pH 10.5 (blue) Ready-to-use reagent. Prepared with ACS reagent grade Thymololphthalein and Reagent Alcohol. Suitable for laboratory use.
Product Overview
Thymolphthalein is a colorless-to-blue pH indicator used in analytical chemistry for identifying strongly basic conditions. It exhibits a sharp color transition from colorless to deep blue between pH 9.3 and 10.5, making it ideal for titrations involving strong bases or for use in alkaline buffer systems.
Due to its vivid color change and minimal interference at neutral or acidic pH levels, Thymolphthalein is especially useful in back titrations, alkalinity tests, and cleaning solution verification. It is available in powder or solution form and dissolves in alcohol for most analytical uses.
Key Features:
- pH transition range: 9.3 (colorless) to 10.5 (blue)
- Strong color contrast for high-pH detection
- Compatible with alcoholic solutions for easy formulation
- Ideal for strong base titration endpoints
- Stable in dry form and under proper storage conditions
Applications:
- Acid-base titrations involving strong bases
- Verification of alkaline cleaners and detergents
- Analytical testing of buffer systems in basic ranges
- Educational demonstrations of high-pH indicators
- Water quality testing for high alkalinity
Thymolphthalein provides sharp, reliable visual feedback in basic environments, making it a preferred indicator for detecting high pH in a wide range of chemical analyses.
