Phenolphthalein

Phenolphthalein is a chemical compound used as an acid-base indicator. It is used to detect the presence of acids and bases in a solution. It is colorless in an acidic solution, and pink in a basic solution. It is used in acid-base titrations to determine the concentration of a base or an acid in a solution. It is also used as a laxative, although it has largely been replaced by other compounds.
