Bromocresol Green ke eng ka CAS 76-60-8?

Botala ba Bromocresol bo qhibiliha hanyane metsing mme bo qhibiliha ka har'a ethanol, ether, ethyl acetate le benzene. Kaha bo bonolo haholo ho alkali, botala ba Bromocresol bo fetoha 'mala o ikhethang oa boputsoa-botala ha bo kopana le litharollo tsa metsi tsa alkaline. Botala ba Bromocresol bo ka sebelisoa e le sesupo, bo hlaha bo le mosehla ho pH 3.8 le boputsoa-botala ho pH 5.4.

Kopo

1. Bromocresol e tala ke sesebelisoa sa ho daea lisele
2. Botala ba Bromocresol ke sesupo sa motheo wa asiti, pH e fetoha ho tloha ho 3.8 (mosehla) ho isa ho 5.4 (boputswa-botala)
3. Letswai la sodium le letala la Bromocresol le sebediswa haholo ho fumana hore na acidity le alkalinity di na le mmala ofe. Tharollo ya sodium ya Bromocresol green e sebediswa e le moemedi wa colorimetric bakeng sa ho lekanya boleng ba pH ka spectrophotometry. E sebediswa e le reagent bakeng sa chromatography e tshesane ho fumana aliphatic hydroxyacids le alkaloids, mme e le moemedi wa ho ntsha le ho arola bakeng sa ho fumana hore na di-cation tsa ammonium tsa quaternary di a fumaneha jwang.
