Phenolphthalein CAS 77-09-8 ke eng?

Phenolphthalein ke asiti e fokolang ea organic, e hlahang e le likristale tse tšoeu kapa tse mosehla hanyane mochesong oa kamore. Phenolphthalein 77-09-8 ha e na monko ebile ha e na tatso. Phenolphthalein 77-09-8 e thata ho qhibiliha ka metsing empa e qhibiliha habonolo ka joala (ethanol) le ether. Phenolphthalein e qhibiliha ka tharollong ea joala ho etsa sesupo sa acid-base. Phenolphthalein 77-09-8 ha e na 'mala ka tharollong ea asiti 'me e khubelu ka tharollong ea alkali kapa alkali metal carbonate. Leha ho le joalo, haeba e le ka tharollong e matla ea alkali, e tla hlahisa trimetallic acid e se nang 'mala. Letsoai, 'mala o mofubelu oa fela

1. Lisebelisoa tse tala tsa meriana bakeng sa indasteri ea meriana: li loketse ho pipitleloa ka tloaelo le ka manganga, li fumaneha ka matlapa, li-suppository le mefuta e meng ea litekanyetso.

2. Phenolphthalein e sebediswang tlhahisong ya tlhaho: phofo ya phenolphthalein e sebediswang haholo bakeng sa polasetiki ya maiketsetso, haholoholo bakeng sa tlhahiso ya di-polymer tsa naphthyridine polyaryl ether ketone polyaryl ether ketone. Mofuta ona wa polymer o na le kganyetso e ntle ya mocheso, kganyetso ya metsi, le kganyetso ya dikhemikhale. Ka lebaka la kganyetso ya yona ya mafome, kganyetso ya ho tsofala ha mocheso le tshebetso e ntle le ho bopeha hantle, difaeba, dikobo le thepa e kopaneng e entsweng ka yona di tla sebediswa haholo disebedisweng tsa elektroniki, disebedisweng tsa mechini, dipalangweng.

3. Phenolphthalein e sebediswang e le sesupo sa motheo wa asiti, sesupo sa titration ya ditharollo tse seng tsa metsi, le reagent bakeng sa tlhahlobo ya chromatographic.
