Phenolphthalein cas 77-09-8 ke eng?

Phenolphthalein ke acid e fokolang ea tlhaho, e hlahang e le likristale tse ntle tse tšoeu kapa tse mosehla hanyenyane mocheso oa kamore. Ha e na monko ebile ha e latsoehe. Ho thata ho qhibiliha ka metsing empa ho bonolo ho qhibiliha joala (ethanol) le ether. E qhibiliha ka tharollo ea joala ho etsa pontšo ea acid-base. Ha e na 'mala ka tharollo ea asiti le e khubelu ka tharollo ea alkali kapa tharollo ea alkali metal carbonate. Leha ho le joalo, haeba e le ka har'a motsoako oa alkali, e tla hlahisa acid e se nang 'mala ea trimetallic. letsoai, 'mala o mofubelu oa fela

1. Lisebelisoa tsa lihlahisoa tsa meriana bakeng sa indasteri ea meriana: tse loketseng bakeng sa ho qeta tloaelo le manganga, tse fumanehang matlapeng, li-suppositories le mefuta e meng ea litekanyetso.

2. Phenolphthalein e sebelisetsoang ho kopanya lintho tse phelang: haholo-holo e sebelisetsoang li-plastiki tsa maiketsetso, haholo-holo bakeng sa motsoako oa naphthyridine polyaryl ether ketone polyaryl ether ketone polymers. Mofuta ona oa polymer o na le khanyetso e ntle ea mocheso, ho hanyetsa metsi, le khanyetso ea lik'hemik'hale. Ka lebaka la ho hanyetsa ha kutu, ho hanyetsa botsofali ba mocheso le ts'ebetso e ntle le sebopeho, likhoele, liaparo le lisebelisoa tse entsoeng ho tloha ho eona haufinyane li sebelisoa haholo lisebelisoa tsa elektroniki, lisebelisoa tsa mochini, lipalangoang, sefofane, boenjiniere ba matla a athomo le masimo a sesole.

3. Phenolphthalein e sebelisoang e le sesupo sa acid-base, sesupo sa titration ea litharollo tse se nang metsi, le reagent bakeng sa tlhahlobo ea chromatographic.
