Zatsopano Zotentha Thymolphthalein CAS 125-20-2 za Zizindikiro za Acid-Base
Zida zoyendetsedwa bwino, gulu lodziwa bwino ntchito yogulitsa, ndi makampani abwino ogulira pambuyo pogulitsa; Ndifenso mamembala akuluakulu abanja, aliyense amatsatira "kugwirizana, kudzipereka, kulekerera" kwa kampani yathu pazinthu zatsopano zotentha.ThymolphthaleinCAS 125-20-2 ya Zizindikiro za Acid-Base, Kuti tiwonjezere kwambiri ubwino wautumiki wathu, kampani yathu imatumiza zida zambiri zamakono zakunja. Takulandirani makasitomala ochokera kunyumba ndi kunja kuti alumikizane ndikufunsa mafunso!
Zida zoyendetsedwa bwino, gulu logulitsa zinthu laluso, ndi makampani abwino kwambiri otsatsa malonda; Ndifenso mamembala akuluakulu abanja, aliyense amatsatira mgwirizano wa bungweli, "kugwirizana, kudzipereka, kulekerera" kwa , Mwa kuphatikiza kupanga ndi magawo amalonda akunja, titha kupereka mayankho athunthu kwa makasitomala potsimikizira kuti zinthu zikufika pamalo oyenera panthawi yoyenera, zomwe zimathandizidwa ndi zomwe takumana nazo zambiri, luso lathu lopanga zinthu mwamphamvu, mtundu wokhazikika, mitundu yosiyanasiyana ya zinthu komanso kuwongolera momwe makampani amagwirira ntchito komanso ntchito zathu zokhwima zisanachitike komanso zitatha kugulitsa. Tikufuna kugawana nanu malingaliro athu ndikulandila ndemanga ndi mafunso anu.
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.
Zinthu zimapakidwa m'thumba, 25kg/ng'oma
Zida zoyendetsedwa bwino, gulu logulitsa zinthu la akatswiri, ndi makampani abwino otsatsa malonda; Ndifenso mamembala akuluakulu abanja, aliyense amatsatira "kugwirizana, kudzipereka, kulekerera" kwa kampani yathu pazinthu zatsopano zotchuka za Thymolphthalein CAS 125-20-2 za Zizindikiro za Acid-Base, Kuti tiwonjezere kwambiri ubwino wautumiki wathu, kampani yathu imatumiza zida zambiri zapamwamba zakunja.

Zogulitsa Zatsopano Zotentha Thymolphthalein ndi CAS 125-20-2, Mwa kuphatikiza kupanga ndi magawo amalonda akunja, titha kupereka mayankho athunthu kwa makasitomala potsimikizira kuti zinthu zoyenera zimaperekedwa pamalo oyenera panthawi yoyenera, zomwe zimathandizidwa ndi zomwe takumana nazo zambiri, luso lamphamvu lopanga, mtundu wokhazikika, mitundu yosiyanasiyana ya zinthu komanso kuwongolera momwe makampani amagwirira ntchito komanso ntchito zathu zokhwima zisanachitike komanso zitatha kugulitsa. Tikufuna kugawana nanu malingaliro athu ndikulandila ndemanga ndi mafunso anu.
