Kapangidwe Kodziwika Kwambiri ka Chizindikiro cha pH cha Chemical Reagent 99% Thymolphthalein CAS 125-20-2
Kukula kwathu kumadalira zida zapamwamba, maluso abwino kwambiri komanso mphamvu zaukadaulo zomwe zimalimbikitsidwa nthawi zonse kuti tipeze mawonekedwe abwino a Chemical Reagent pH Indicator 99%Thymolphthalein CAS 125-20-2Tiyeni tigwirizane kuti tipange tsogolo labwino kwambiri. Tikukulandirani moona mtima kuti mudzacheze ndi kampani yathu kapena kutiyimbira foni kuti tikuthandizeni!

Ndipo kutengera mtundu wabwino kwambiri, mtengo wabwino, ndi ntchito yabwino kwambiri, talandira mayankho abwino kuchokera kwa makasitomala akunja. Mwalandiridwa kuti mudzatigwirizane nafe kuti mupeze mwayi ndi maubwino ambiri. Timalandira makasitomala, mabungwe amalonda ndi abwenzi ochokera mbali zonse za dziko lapansi kuti atilankhule ndikupempha mgwirizano kuti tipindule tonse.
ThymolphthaleinDzina la sayansi la "3,3-bis(4-hydroxy-5-isopropyl-2-methylphenyl)-phthalide", lomwe ndi reagent yachilengedwe. Fomula ya mankhwala ndi C28H30O4, ndipo kulemera kwa molekyulu ndi 430.54. Ndi ufa woyera wa kristalo. Umasungunuka mosavuta mu ether, acetone, sulfuric acid ndi alkaline solutions, ndipo susungunuka m'madzi. Nthawi zambiri umagwiritsidwa ntchito ngati chizindikiro cha acid-base, ndipo pH yake yosintha mtundu ndi 9.4-10.6, ndipo mtundu umasintha kuchoka pa wopanda mtundu kupita ku buluu. Ikagwiritsidwa ntchito, nthawi zambiri imakonzedwa kukhala yankho la ethanol la 0.1% 90%. Nthawi zambiri imakonzedwa ndi zizindikiro zina kuti ipange chizindikiro chophatikizana chofatsa kuti mtundu wake wosintha mtundu ukhale wocheperako komanso kuti kuwonera kumveke bwino.

Thymolphthalein nthawi zambiri imagwiritsidwa ntchito ngati chizindikiro cha acid-base, yokhala ndi pH ya kusintha kwa mtundu wa 9.4 mpaka 10.6, komanso kusintha kwa mtundu kuchokera ku wopanda mtundu kupita ku buluu. Ikagwiritsidwa ntchito, nthawi zambiri imakonzedwa ngati yankho la ethanol la 0.1% 90%, ndipo nthawi zambiri imasakanizidwa ndi zizindikiro zina kuti ipange chizindikiro chosakanikirana kuti mtundu wake ukhale wocheperako komanso womveka bwino kuti uwonekere. Mwachitsanzo, chizindikiro chomwe chimapangidwa posakaniza yankho la ethanol la 0.1% la reagent iyi ndi yankho la ethanol la 0.1% la phenolphthalein sichikhala ndi mtundu mu yankho la acidic, chofiirira mu yankho la alkaline, ndipo chimakwera pa pH 9.9 (malo osinthira mtundu), zomwe ndizosavuta kuziwona.
