pH 8.0 (colorless) - pH 10.0 (pink) Ready-to-use reagent. Prepared with ACS reagent grade Phenolphthalein and Reagent Alcohol. Suitable for laboratory use.
Product Overview
Phenolphthalein is one of the most commonly used pH indicators in analytical chemistry, valued for its clear and sharp color transition in strong acid–strong base titrations. It is colorless in acidic solutions and turns bright pink in basic conditions, with a transition range between pH 8.0 and 10.0.
Due to its high visibility and rapid response, Phenolphthalein is widely used in laboratory titrations, quality control testing, water analysis, and as a component in commercial formulations such as laxatives and leak detection agents. It is available in both powder and ready-to-use solution forms.
Key Features:
- pH transition range: 8.0 (colorless) to 10.0 (pink)
- Sharp, easily visible endpoint for titrations
- Ideal for strong acid–strong base reactions
- Available in multiple concentrations and formats
- Stable under standard laboratory conditions
Applications:
- Acid-base titrations in chemistry laboratories
- Water hardness and alkalinity testing
- Educational use in chemistry instruction
- pH indication in industrial chemical processing
- Component in forensic and diagnostic test kits
Phenolphthalein remains a trusted and effective tool for clear, precise pH detection in a variety of analytical and instructional settings.
