Phenolphthalein is an organic compound with the molecular formula C20H14O4. It is typically found as a white crystalline powder. When phenolphthalein is dissolved in ethanol at a concentration of 1%, and the ethanol itself is at 95% concentration (with 5% water), it forms a clear, colorless solution. This solution acts as a pH indicator, changing color based on the pH level of the environment: it is colorless in acidic solutions and turns pink to fuchsia in basic solutions, with the color change occurring around a pH range of 8.2 to 10.0. Phenolphthalein 1% in 95% ethanol is a chemical solution that is extensively used in scientific, educational, and industrial fields.
