Phenolphthalein

Phenolphthalein is a sensitive pH indicator with the formula C₂₀H₁₄O₄.

Often used in titrations, it turns from colorless in acidic solutions to pink in basic solutions. If the concentration of indicator is particularly strong, it can appear purple.

In strongly basic solutions, phenolphthalein's pink color undergoes a rather slow fading reaction and becomes colorless again.
