Phenolphthalein ndi organic pawiri ndi chilinganizo C20H14O4. Ndi ufa wa crystalline woyera mpaka wachikasu pang'ono womwe susungunuka m'madzi kutentha kokwanira, koma sungunuka mu zosungunulira organic monga alcohols, ma ketones ndi esters. Phenolphthalein ndi chizindikiro, Amagwiritsidwa ntchito kwambiri pakupanga acid-base titration. Yankho lake ndi lopanda mtundu, pinki mu zofooka za alkaline kapena zandale, ndipo kusintha kwakukulu kwa mtundu kumachitika pamene pH ili 8.2 kapena wamkulu. Mitundu yosinthira mitundu yamankhwala a phenolphthalein ndi yoyenera pazotsatira za acid-base titration, monga neutralization amphamvu zidulo ndi maziko. Chifukwa cha kusintha kwake kwamtundu womveka komanso kukhudzidwa kwakukulu, phenolphthalein amagwiritsidwa ntchito kwambiri poyesera mankhwala, kusanthula ndi kuzindikira khalidwe.
Product Parameter
Kugwiritsa ntchito
1. Chizindikiro cha acid-base titration: Phenolphthalein ndi chimodzi mwazodziwika bwino za acid-base titration. Nthawi zambiri amagwiritsidwa ntchito kuyesa acidity ndi alkalinity ya yankho, ndipo ndiyoyenera makamaka kusinthasintha pakati pa njira ya acidic ndi yankho lamphamvu la alkali. Phenolphthalein imawoneka yopanda mtundu pansi pa mikhalidwe yofooka ya acidic komanso ndale, ndi mtundu wosiyana wapinki pansi pamikhalidwe yamchere, ndipo kusintha kwamtundu uku kumagwiritsidwa ntchito nthawi zambiri kuti azindikire kumapeto kwa titration.
2. Kusanthula mankhwala: Phenolphthalein angagwiritsidwe ntchito ngati chizindikiro cha oxalic acid quantification ndi magnesium ion kuzindikira. Mu quantification wa oxalic acid, phenolphthalein ngati chizindikiro angasonyeze ndende ya oxalic acid. Kuzindikira kwa magnesium ion, phenolphthalein akhoza kusonyeza kukhalapo ndi ndende ya magnesium ayoni.
3. Kuyesera kwa biochemical: Phenolphthalein ikhoza kugwiritsidwa ntchito ngati chizindikiritso cha kuyesa kwachilengedwe kwazinthu zina zamoyo kuti zizindikire kukhalapo kapena kusakhalapo kwa zinthu., monga kuzindikira momwe ma enzyme amagwirira ntchito komanso mapangidwe a metabolites.
4. Utoto ndi utoto: Phenolphthalein itha kugwiritsidwa ntchito ngati zopangira zopangira utoto wamitundu ndi utoto.. Itha kugwiritsidwa ntchito ngati utoto popereka ulusi ndi zinthu zina zamitundu yosiyanasiyana.
