Product Description
Phenolphthalein is a widely used pH indicator in laboratories, known for its sharp color change from colorless to pink in the pH range of 8.2 to 9.8. This Merck product, with catalog number 1.07233.0100, is a reliable choice for students, researchers, and educators conducting acid-base titrations or other pH-sensitive experiments.
The indicator is supplied in a convenient 100g pack, ensuring you have an adequate supply for multiple experiments. Its lab-grade purity guarantees accurate and consistent results, making it a staple in chemistry labs across India. Whether you’re setting up a school lab or conducting advanced research, this phenolphthalein indicator meets the highest standards of quality.
When dissolved in alcohol, phenolphthalein forms a clear solution that remains colorless in acidic and neutral conditions but turns bright pink in alkaline solutions. This distinct color transition makes it easy to identify the endpoint in titrations, ensuring precise measurements. The indicator is stable under normal lab conditions, but it’s always best to store it in a cool, dry place away from direct sunlight.
