酚酞作为一种常用指示剂,广泛使用于酸碱滴定过程中。通常情况下酚酞遇酸溶液不变色,遇中性溶液也不变色，遇碱溶液变红色。然而,酚酞在强碱中由红色迅速退为无色,而在浓酸中也会变色,在稀酸溶液中酚酞滴加过量造成沉淀,使溶液变成白色浑浊。（这是由于酒精易溶于水，使试剂中难溶于水的酚酞析出的缘故。)
Phenolphthalein is a chemical compound with the formula C20H14O4 and is often written as "HIn" or "phph" in shorthand notation. Phenolphthalein is often used as an indicator in acid–base titrations. For this application, it turns colorless in acidic solutions and pink in basic solutions. It belongs to class of dyes known as phthalein dyes.
