Bromocresol ntsuab yaj me ntsis hauv dej thiab yaj hauv ethanol, ether, ethyl acetate, thiab benzene. Nws rhiab heev rau alkali, Bromocresol ntsuab hloov xim xiav-ntsuab tshwj xeeb thaum ntsib cov kua alkaline. Bromocresol ntsuab siv tau ua qhov qhia, tshwm daj ntawm pH 3.8 thiab xiav-ntsuab ntawm pH 5.4.

1.Bromocresol ntsuabyog tus neeg sawv cev rau cov xim ntawm tes
2.Bromocresol ntsuabyog qhov qhia txog Acid-base, pH hloov xim ntau yam 3.8 (daj) txog 5.4 (xiav-ntsuab)
3. Bromocresol ntsuab sodium ntsev feem ntau siv rau hauv kev txiav txim siab xim ntawm acidity thiab alkalinity. Bromocresol ntsuab sodium ntsev kua yog siv los ua tus neeg sawv cev colorimetric rau kev ntsuas pH tus nqi los ntawm spectrophotometry. Siv ua tus reagent rau nyias txheej chromatography los txiav txim siab aliphatic hydroxyacids thiab alkaloids, thiab ua tus neeg sawv cev rho tawm thiab sib cais rau kev txiav txim siab photometric ntawm quaternary ammonium cations.
