Tsis tas li ntawd, pH ntau npaum li cas rau Bromothymol xiav?
Bromothymol xiav yog siv tau thaum siv ntawm a pH ntau yam ntawm 6.0-7.6.
Tsis tas li ntawd, vim li cas cov xim ntawm Bromothymol xiav hloov? Cov bromothymol xiav hloov pauv xim vim tias muaj tshuaj lom neeg nrog cov pa roj carbon dioxide. Tom qab qhov kev ua si bromothymol xiav tig ntsuab sai dua. Qhov no yog vim tias cov pa roj carbon dioxide raug tshem tawm mus rau hauv nws sai dua, vim yog kev tawm dag zog.
Ib yam li ntawd, koj tuaj yeem nug, Dab tsi Xim yog Bromothymol xiav hauv lub hauv paus?
| Qhov taw qhia | Acid Xim | Base Xim |
|---|---|---|
| Bromothymol xiav | daj | xiav |
| Phenol liab | daj | liab |
| Ci ntsa iab daj | daj | txiv kab ntxwv |
| Cresol liab | daj | liab |
Cov xim ntawm BTB qhia li cas?
Bromothymol xiav (BMB) yog qhov taw qhia zas xim uas tig daj nyob rau hauv lub xub ntiag ntawm acid. Thaum carbon dioxide ntxiv rau cov tshuaj, nws tsim carbonic acid, txo cov pH ntawm cov tshuaj. BMB yog xiav thaum pH siab dua 7.6, ntsuab thaum pH nyob nruab nrab ntawm 6-7.6, thiab daj thaum pH tsawg dua 6.

Cov xim dab tsi Bromothymol xiav tig rau hauv cov tshuaj nruab nrab?
Cov kev siv tseem ceeb ntawm bromothymol xiav yog rau kev kuaj pH thiab kuaj cov photosynthesis thiab ua pa. Bromothymol xiav muaj xim xiav thaum nyob rau hauv tej yam kev mob (pH tshaj 7), xim ntsuab nyob rau hauv nruab nrab tej yam kev mob (pH ntawm 7), thiab daj xim nyob rau hauv acidic tej yam kev mob (pH nyob rau hauv 7)
Yuav ua li cas tshwm sim rau cov xim ntawm Bromothymol xiav kua?
Cov pa roj carbon dioxide hauv cov tub ntxhais kawm ua tsis taus pa dissolves hauv cov tshuaj bromothymol xiav. 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
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
Thaum lub ntim ntawm ib qho piv txwv ntawm cov pa roj yog txo lub siab ntawm cov qauv ntawm cov pa roj?
Kev txo qis Cov pa roj sib xyaw txoj cai hais tias lub siab ntawm cov pa roj yog inversely cuam tshuam nrog lub ntim thiab ncaj qha ntsig txog qhov kub thiab txias. Yog tias qhov kub thiab txias yog nyob tas li, qhov sib npaug raug txo rau Boyle txoj cai. Yog li ntawd, yog tias koj txo qhov siab ntawm cov roj av tas li, nws qhov ntim yuav nce ntxiv
Lub neej ntawm lub hnub qub xiav xiav yog dab tsi?
Lub hnub qub nruab nrab zoo li peb lub hnub yuav kav ntev txog 12 billion xyoo, thaum lub ntuj xiav supergiant yuav tawg nrog ob peb puas lab xyoo
