In the realm of chemical analysis, precision is paramount. For accurate acid-base titrations, selecting the correct pH indicator is a critical step. Among the most commonly used is Phenolphthalein (CAS 77-09-8), a staple in laboratories worldwide. This article aims to guide professionals on understanding and utilizing Phenolphthalein effectively, and how to source it from a dependable manufacturer.

Phenolphthalein is a weak acid that exhibits a distinct color change within a specific pH range. Typically, it remains colorless in acidic solutions (pH < 8.3) and turns a vibrant pink or fuchsia in basic solutions (pH > 8.3). This clear visual transition makes it an excellent choice for titrations involving strong acids and strong bases, or weak acids and strong bases. Understanding this transition range is key to interpreting your titration results accurately.

When sourcing Phenolphthalein, consider its purity and origin.

Beyond its primary use in titration, Phenolphthalein has found other interesting applications. It's used in the construction industry to test the carbonation depth of concrete, a vital factor in its durability. In educational settings, it serves as a vivid demonstration tool for teaching chemical concepts related to pH and chemical reactions. For those looking to purchase Phenolphthalein, inquire about its availability and pricing from reliable suppliers in your region or directly from manufacturers in China.
