Cov kev siv tseem ceeb ntawm bromothymol xiav yog rau kev kuaj pH thiab kuaj cov photosynthesis thiab ua pa. Bromothymol xiav muaj xiav xim thaum nyob rau hauv tej yam kev mob (pH tshaj 7), ntsuab xim nyob rau hauv nruab nrab tej yam kev mob (pH ntawm 7), thiab ib tug daj xim nyob rau hauv acidic tej yam kev mob (pH qis dua 7).

Ib yam li ntawd, lub hom phiaj ntawm Bromothymol xiav yog dab tsi?

Bromothymol xiav (tseem hu ua bromothymol sulfone phthalein thiab BTB) yog pH qhia. Nws feem ntau yog siv rau hauv daim ntawv thov uas yuav tsum tau ntsuas cov tshuaj uas yuav muaj qhov nruab nrab pH (ze 7). Ib qho kev siv feem ntau yog ntsuas qhov muaj carbonic acid hauv cov kua.

Ib yam li ntawd, yuav ua li cas thaum Bromothymol xiav ntxiv rau lub hauv paus? Bromthymol xiav hloov xim tshaj pH ntau ntawm 6.0 (daj) txog 7.6 ( xiav ). Tsawg theem ntawm carbon dioxide los yog acid nyob rau hauv kev daws nrog bromothymol xiav qhov taw qhia yuav tshwm xiav . Raws li qib ntawm carbon dioxide los yog acid nce, cov tshuaj yuav maj mam coj mus rau ib tug daj tint.

Yog li ntawd, Bromothymol Blue yog dab tsi thiab nws siv los ntsuas qhov ua pa ntawm tes li cas?

Cellular ua pa xav tau cov pa oxygen (uas ua pa rau hauv) thiab tsim cov pa roj carbon dioxide (uas ua pa tawm). Kev tsim cov pa roj carbon dioxide tuaj yeem ntsuas tau los ntawm kev ua pa los ntawm cov quav cab rau hauv cov tshuaj bromothymol xiav (BTB). BTB yog qhov ntsuas acid; thaum nws reacts nrog acid nws tig los ntawm xiav rau daj.

Cov pa roj carbon dioxide cuam tshuam dab tsi rau Bromothymol xiav?

Cov carbon dioxide nyob rau hauv tus me nyuam txoj kev ua tsis taus pa dissolves nyob rau hauv lub bromothymol xiav daws. Cov carbon dioxide tuaj yeem cuam tshuam nrog dej thiab tsim carbonic acid, ua kom cov kua qaub me ntsis. Bromothymol xiav yuav hloov mus rau ntsuab thiab ces daj nyob rau hauv acids.
