Phenolphthalein

Phenolphthalein is an organic compound with the chemical formula C20H14O4.
It is a weak acid that is often used as an indicator in acid-base titrations.
In acidic solutions, phenolphthalein is colorless.
However, in basic solutions, it turns pink.
This change in color is due to the deprotonation of phenolphthalein, which forms a pink anion.
