Menene Phenolphthalein CAS 77-09-8?

Phenolphthalein wani sinadari ne mai rauni na halitta, wanda ke bayyana a matsayin farin ko ɗan rawaya mai laushi a zafin ɗaki. Phenolphthalein 77-09-8 ba shi da ƙamshi kuma ba shi da ɗanɗano. Phenolphthalein 77-09-8 yana da wahalar narkewa a cikin ruwa amma yana narkewa cikin sauƙi a cikin barasa (ethanol) da ether. Ana narkar da Phenolphthalein a cikin maganin barasa don yin alamar tushen acid. Phenolphthalein 77-09-8 ba shi da launi a cikin maganin acid kuma ja a cikin maganin alkali ko maganin carbonate na ƙarfe na alkali. Duk da haka, idan yana cikin maganin alkali mai ƙarfi, zai samar da sinadarin trimetallic mara launi. gishiri, launin ja yana shuɗewa.
