Phenolphthalein is a chemical compound with the molecular formula C20H14O4. It is a synthetic organic dye that exhibits weak acidity and exists in both acid and base forms, displaying different colors based on the pH of its solution.

 

 

1. pH Indicator: Phenolphthalein is widely used as a pH indicator in chemical and biochemical laboratories. It turns pink in alkaline solutions (pH above 8.2) and remains clear in acidic solutions.
2. Medical Uses: In medicine, it has been used as a laxative, where it works by stimulating intestinal muscle contractions. However, its use in this context has declined due to safety concerns.
3. Dyeing and Staining: It is also employed in dyeing and staining processes, particularly in the textile and biological staining industries.

1. Color Change Indicator: The primary function of phenolphthalein is to indicate changes in pH levels through visible color changes, making it useful in titration and other analytical chemistry techniques.
2. Laxative Effect: In its medical application, phenolphthalein functions by stimulating the nerves in the intestinal wall, leading to contractions that help move stool through the intestines.
3. Staining Agent: As a staining agent, phenolphthalein can selectively stain certain structures or components in biological samples, aiding in their visualization and identification under a microscope.
