Product Overview

Phenolphthalein indicator solution is a widely used synthetic dye that serves as a reliable pH indicator in laboratory settings. This colorless-to-pink transition reagent is highly sensitive, changing hue at a pH range of 8.3 to 10.0, making it indispensable for acid-base titrations and neutralizations. The solution is prepared in a stable alcohol-water mixture, ensuring consistent performance and long shelf life when stored properly. Its high purity and precise formulation guarantee accurate results, eliminating false readings caused by impurities. The indicator is compatible with most aqueous solutions and does not interfere with common titration reactions. As a non-toxic, water-soluble compound, it offers safe handling for routine laboratory procedures. The 125 ml packaging provides an optimal balance between sufficient quantity for multiple experiments and convenient storage. This laboratory-grade phenolphthalein solution meets stringent quality standards, delivering reproducible color changes that clearly mark titration endpoints. Its versatility extends to both qualitative and quantitative analyses, making it a staple in chemical laboratories.

FAQs

1. How does phenolphthalein indicator solution change color in different pH conditions?

The solution remains colorless in acidic conditions (pH 10.0), with a transition range between 8.3 to 10.0.

2. Can this indicator be used with non-aqueous solvents?

Phenolphthalein is primarily designed for aqueous solutions. For non-aqueous titrations, specialized indicators may be more appropriate.

3. What is the shelf life of this phenolphthalein solution when unopened?

When stored in a cool, dark place with the cap tightly sealed, the unopened solution typically maintains stability for 24 months from the date of manufacture.

4. Does this solution require any special disposal procedures?

While non-toxic, it should be disposed of according to standard laboratory chemical waste protocols, avoiding direct release into drains or environment.
