Lub ntsiab siv ntawm bromothymol xiav yog rau kev kuaj pH thiab kuaj photosynthesis thiab ua pa. Bromothymol xiav muaj ib xiav xim thaum nyob hauv yooj yim tej yam kev mob (pH tshaj 7), ntsuab xim hauv nruab nrab cov xwm txheej (pH ntawm 7), thiab daj xim hauv acidic cov xwm txheej (pH qis dua 7).
Yog li ntawd, cov xim twg Bromothymol xiav tig rau hauv cov kev daws teeb meem nruab nrab?
Bromothymol xiav ua raws li cov kua qaub tsis muaj zog hauv cov tshuaj. Nws tuaj yeem yog hauv daim ntawv protonated lossis deprotonated, tshwm daj los yog xiav, feem. Nws yog ci aquamarine los ntawm nws tus kheej, thiab ntsuab-xiav nyob rau hauv ib tug nruab nrab daws.
Ib yam li ntawd, Bromothymol Blue Solution yog dab tsi? Kev piav qhia. Qhov no yog 0.1% aqueous bromothymol xiav tov (tseem hu ua Bromthymol Xiav ) yog ib qho kev qhia pH feem ntau siv. Bromthymol xiav hloov xim tshaj pH ntau ntawm 6.0 (daj) txog 7.6 ( xiav ). Nws yog qhov qhia tau zoo ntawm cov pa roj carbon dioxide yaj (CO2) thiab lwm yam tsis muaj zog acidic kev daws teeb meem.
Ua raws li qhov xav tau, cov xim dab tsi Bromothymol xiav tig rau hauv lub hauv paus?
Bromthymol xiav yog cov kua qaub tsis muaj zog. Nws tuaj yeem ua rau hauv cov kua qaub lossis hauv paus, nyob ntawm pH ntawm cov tshuaj. Qhov no reagent yog daj nyob rau hauv acidic daws, xiav nyob rau hauv cov ntsiab lus daws teeb meem thiab ntsuab nyob rau hauv nruab nrab tov.
Dab tsi yog lub luag haujlwm rau kev hloov xim hauv Bromothymol xiav kua?
Cov pa roj carbon dioxide hauv cov tub ntxhais kawm ua tsis taus pa dissolves hauv bromothymol xiav tov . Cov pa roj carbon dioxide tuaj yeem cuam tshuam nrog dej thiab tsim carbonic acid, ua rau cov daws me ntsis acidic. Bromothymol xiav yuav hloov mus rau ntsuab thiab ces daj nyob rau hauv acids.

Cov pa roj carbon dioxide tuaj yeem cuam tshuam nrog dej thiab tsim carbonic acid, ua rau cov kua qaub me ntsis. Bromothymol xiav yuav hloov mus rau ntsuab thiab ces daj nyob rau hauv acids
Qhov nruab nrab nruab nrab ntawm lub ntiaj teb yog dab tsi?
Lub teb chaws qhov ntsuas kub yog 2.91 ° C (5.24 ° F) saum toj no 1961-1990 qhov nruab nrab, tawg cov ntaub ntawv yav dhau los tau teev tseg hauv 2013 los ntawm 0.99 ° C (1.78 ° F)
Cov xim dab tsi yog cov hlwb feem ntau ua ntej siv thawj cov xim rau cov txheej txheem Gram stain?
Ua ntej, siv lead ua violet, thawj stain, yog siv rau lub tshav kub-tso smear, muab tag nrho cov hlwb xim liab
Koj pom qhov nruab nrab thiab nruab nrab hauv tableau li cas?
Kev sib txuas lus cov ntaub ntawv nrog Tableau los ntawm Ben Jones Qhov nruab nrab (lossis nruab nrab) yog txiav txim siab los ntawm kev suav tag nrho cov txiaj ntsig hauv cov ntaub ntawv teev thiab faib los ntawm tus lej ntawm qhov tseem ceeb. Qhov nruab nrab yog tus nqi nruab nrab hauv cov ntaub ntawv teev nyob rau hauv uas qhov tseem ceeb tau muab tso rau hauv kev txiav txim ntawm qhov loj
Koj ua li cas sib npaug redox cov tshuaj tiv thaiv hauv acidic thiab nruab nrab nruab nrab?
Acid Conditions Solution. Kauj Ruam 1: Sib cais ib nrab cov lus teb. Kauj Ruam 2: Ntsuas cov ntsiab lus uas tsis yog O thiab H. Kauj Ruam 3: Ntxiv H2O kom sib npaug ntawm cov pa. Kauj Ruam 4: Sib npaug hydrogen los ntawm kev ntxiv protons (H +). Kauj Ruam 5: Ntsuas tus nqi ntawm txhua qhov sib npaug nrog electrons. Kauj Ruam 6: Ntsuas cov tshuaj tiv thaiv kom cov electrons sib npaug
