  • 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. Phenolphthalein is slightly soluble in water and usually is dissolved in alcohols for use in experiments

Answer:

Phenolphthalein is a weak organic acid. Its undissociated molecule (HPh) is colourless while its ion (Ph

) is pink in colour. pH range of Phenolphthalein is 8−9.8. In acid base titration phenolphthalein is used as indicator. As the concentration of OH

ions increases a little, solution turns pink from colourless giving its end point.
