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.
Xav txog qhov no, dab tsi xim yog Bromothymol xiav hauv cov ntsiab lus daws teeb meem?
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 nyob rau hauv acidic tej yam kev mob (pH qis dua 7).
Tsis tas li ntawd, vim li cas Bromothymol xiav ntsuab hauv cov kev daws teeb meem nruab nrab? Bromothymol xiav ua raws li tsis muaj zog acid nyob rau hauv daws . Nws tuaj yeem yog hauv daim ntawv protonated lossis deprotonated, tshwm daj lossis xiav , raws. Nws yog xiav ntsuab nyob rau hauv nruab nrab tov . Ib qho nruab nrab ntawm lub tshuab deprotonation yog lub luag haujlwm rau cov xim ntsuab hauv nruab nrab daws (2).
Ib yam li ib tug yuav nug, nws txhais li cas thaum Bromothymol Blue tig daj?
Bromothymol xiav (BMB) yog qhov taw qhia dye 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, daj thaum pH tsawg dua 6.
Puas yog Bromothymol Blue yog qhov qhia tau zoo?
Qhov no yog 0.1% aqueous bromothymol xiav tshuaj (tseem hu ua Bromthymol Xiav ) yog ib qho pH feem ntau siv qhov taw qhia . Bromthymol xiav hloov xim tshaj pH ntau ntawm 6.0 (daj) txog 7.6 ( xiav ). Nws yog ib qhov taw qhia zoo carbon dioxide yaj (CO2) thiab lwm yam tsis muaj zog acidic daws.
Pom zoo:
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)
Cov xim twg yog Bromothymol xiav ntawm pH siab?
daj 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.
Tus qauv yuav pab nrhiav qhov tshwm sim ntawm qhov kev tshwm sim sib xyaw li cas?
Lub ntsiab lus ntawm Qhov Muaj Peev Xwm Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej yog ib qho uas muaj ntau tshaj li qhov ua tau. Kev txiav txim siab qhov yuav tshwm sim ntawm qhov kev tshwm sim sib xyaw suav nrog kev nrhiav cov lej ntawm qhov tshwm sim ntawm tus kheej cov xwm txheej thiab, yog tias tsim nyog, tshem tawm qhov muaj feem sib tshooj
Yuav ua li cas yog qhov tshwm sim uas ib tug poj niam dig muag xim uas yuav ib tug txiv neej uas tsis pom kev zoo yuav muaj xim dig muag me nyuam?
Yog tias tus poj niam uas muaj lub zeem muag zoo li no (heterozygous rau qhov muag tsis pom xim) yuav ib tug txiv neej ib txwm muaj (XY), cov xeeb ceem hauv qab no tuaj yeem xav tau hauv F2 tiam: ntawm cov ntxhais, 50% yog ib txwm muaj thiab 50% yog cov neeg nqa khoom rau cov kab mob; ntawm cov tub, 50% yog xim dig muag thiab 50% yog qhov pom kev zoo
Yuav ua li cas koj pom qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug?
Txhawm rau xam qhov tshwm sim ntawm qhov tshwm sim tshwm sim tsawg kawg ib zaug, nws yuav yog qhov sib ntxiv ntawm qhov xwm txheej tsis tshwm sim. Qhov no txhais tau hais tias qhov tshwm sim ntawm qhov tshwm sim yeej tsis tshwm sim thiab qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug yuav sib npaug, lossis 100% txoj hauv kev
