Bromothymol xiav (BMB) yog tus 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, thiab daj thaum pH tsawg dua 6.
