Phenolphthalein Usage:  This product is a commonly used acid indicator with the range of color change between pH 8.2 (colorless) to 10.0 (red).  Phenolphthalein is also a drug, can be used as a laxative, acting on the colon for the treatment of constipation.Used as an acid-base indicator;   as irritant laxative for the treatment of constipation. Phenolphthalein is one of those chemicals that is commonly used in the chemistry laboratory to tell if a solution is acidic or alkaline .  These chemicals are called acid - base indicators and used as indicator for acidimetric titrations.   Phenolphthalein exerts laxative effects by stimulating the intestinal mucosa and constricting smooth muscles.
