Phenolphthalein as a pH Indicator: How Does it Work?

Phenolphthalein’s most popular use is as a pH indicator. It can be used by itself, or be an ingredient in universal indicators, alongside thymol blue or methyl red. These mixtures cover a wider range of pH changes.

From a chemical point of view, phenolphthalein works as a pH indicator due to 4 different states in solutions, with different colourations:

  • In strongly acidic conditions (pH<1): orange colour
  • In mildly acidic and near neutral conditions (0<pH<8.2): colourless
  • In alkaline conditions (8.2<pH<12): pink
  • In strongly alkaline conditions (pH>13): colourless

Niche Applications

This compound has found its way into several colour-changing curious applications:

  • When Barbie changes hair colour: Phenolphthalein is commonly used in toys, such as Barbie dolls and others, which involve a colour change. In this case, phenolphthalein is typically mixed with sodium hydroxide, which then can react with carbon dioxide in the air. This reaction results in a pH drop and Barbie can change her hair colour!
  • Hard as concrete: This compound is also used to assess the quality of concrete. Under normal circumstances, concrete has a naturally high pH – around 8.5 – due to reaction with water. In this case, when a phenolphthalein solution is used, concrete turns bright pink. However, if this colour does not appear, it may be a sign of carbonation and deterioration.
