Isaphulelo sekhwalithi ephezulu ye-Phenolphthalein cas 77-09-8
Izinzuzo
- I-Chemical Formula: C20H14O4
- Isisindo samangqamuzana: 318.33 g/mol
- Ukubukeka: I-crystalline powder emhlophe ukuya kokumhlophe
- Iphuzu Elincibilikayo: 258-263°C
- Ukunyibilika: Ayincibiliki emanzini, incibilika otshwaleni, ether, ne-acetic acid
I-Phenolphthalein isetshenziswa ngokuyinhloko njengenkomba kuma-acid-base titration, lapho ikhombisa ukushintsha kombala ukusuka kokungabi mbala kuye kobomvana njengoba i-pH ishintsha isuka ku-acidic iye ku-alkaline.Lesi sici sikwenza kube yigugu kumalabhorethri ezemfundo nasezilungiselelweni ezihlukahlukene zocwaningo, okuqinisekisa ukuzimisela okunembayo kwesiphetho.
Ngaphezu kwalokho, i-phenolphthalein ithola ukusetshenziswa ekuxilongweni kwezokwelapha, ikakhulukazi ekutholeni ukungasebenzi kahle kwamathumbu.Isetshenziswa njenge-laxative, inikeza ikhambi elithambile nelisebenzayo lokukhulula ukuqunjelwa.Lapho idliwe, i-phenolphthalein ishintsha umbala oncike ku-pH ngaphakathi kwamathumbu, ngaleyo ndlela isize ekuhloleni ukusebenza kwamathumbu.
Ngaphezu kokusetshenziswa kwayo kwamakhemikhali nokwelapha, i-phenolphthalein iphinde ithole ukusetshenziswa kwezimonyo nemikhiqizo yokunakekela komuntu siqu.Le nhlanganisela isetshenziswa emakhakheni ezinwele nakwamanye amalungiselelo e-cosmetic, ihlinzeka ngemibala efiselekayo yombala.Ukuzinza nokuhambisana kwayo nezinhlobonhlobo ezihlukahlukene kuyenza ibe yinketho ekahle yokuthuthukisa ukukhanga kobuhle bemikhiqizo yokunakekelwa komuntu siqu.
I-phenolphthalein yethu, ngobumsulwa bayo obuphezulu kanye nekhwalithi engaguquki, ikhiqizwa ngokulandela izindinganiso eziqinile zezimboni.Siqinisekisa ukuqedwa kokungcola nokungcola, sikunikeze umkhiqizo ohlangabezana nokulindelwe okuphezulu.Ngohlelo lwayo olubanzi lwezinhlelo zokusebenza, le phenolphthalein iyithuluzi elibaluleke kakhulu kochwepheshe emkhakheni wamakhemikhali, umuthi, nezimonyo.
Faka i-oda lakho namuhla futhi ujabulele ukusebenza okuyingqayizivele kwe-CAS yethu ye-phenolphthalein: 77-09-8.Thembela ekunembeni nasekuthembekeni kwayo kuzo zonke izidingo zakho zemfundo, ezesayensi, nezimboni.
