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.
Ionized molecules attract other molecules with the opposite charge and repel those with the same charge. Phenolphthalein is a weak acid and is colorless in solution although its ion is pink. ... Adding hydroxide ions (OH-, as found in bases) will change the phenolphthalein into its ion and turn the solution pink.
