Gịnị bụ Phenolphthalein CAS 77-09-8?

Phenolphthalein bụ asịd organic na-adịghị ike, nke na-adị ka kristal ọcha ma ọ bụ odo odo dị ntakịrị na okpomọkụ ụlọ. Phenolphthalein 77-09-8 enweghị isi ma ọ bụ ụtọ. Phenolphthalein 77-09-8 siri ike ịgbaze na mmiri mana ọ na-agbaze ngwa ngwa na mmanya (ethanol) na ether. A na-agbaze Phenolphthalein na ngwọta mmanya iji mee ihe ngosi acid-base. Phenolphthalein 77-09-8 enweghị agba na ngwọta acidic yana ọbara ọbara na ngwọta alkali ma ọ bụ ngwọta alkali metal carbonate. Agbanyeghị, ọ bụrụ na ọ dị na ngwọta alkali a chịkọtara, ọ ga-emepụta acid trimetallic na-enweghị agba. Nnu, agba uhie na-apụ n'anya.
