Phenolphthalein ACS Reagent

Appearance: White powder Density: 1,3 g/cm³ Solubility in other solvents: Insoluble in benzene and hexane; very soluble in ethanol & ether; slightly soluble in DMSO Solubility in water: 400 mg/l Molar mass: 318,31 g/mol Melting point: 260 °C Phenolphthalein is a commonly used pH indicator in acid-base titrations. It remains colorless in acidic solutions and changes to pink in basic solutions (pH above 8.2), making it an effective tool for visually identifying the endpoint of a titration.
