Phenolphthalein bụ organic acid na-adịghị ike, nke na-egosi dị ka kristal dị mma na-acha ọcha ma ọ bụ ntakịrị odo na okpomọkụ. Ọ dịghị isi na enweghị ụtọ. O siri ike igbari na mmiri mana ọ dị mfe soluble na mmanya (ethanol) na ether. A na-agbaze ya na ngwọta mmanya iji mee ihe ngosi acid-base. Ọ bụ enweghị colorless na acidic ngwọta na-acha uhie uhie na alkali ngwọta ma ọ bụ alkali metal carbonate ngwọta. Otú ọ dị, ọ bụrụ na ọ dị na ngwọta alkali, ọ ga-emepụta trimetallic acid na-enweghị agba. nnu, agba uhie na-ada ada
