O le a le Bromocresol Green With CAS 76-60-8?

Bromocresol lanumeamata e fai sina solu i le vai ma solu i le ethanol, eter, ethyl acetate, ma le benzene. E matua maaleale i le alkali, Bromocresol lanu meamata e liliu se lanu lanumoana-lanumeamata faapitoa pe a feagai ma vaifofo alkaline. Bromocresol lanumeamata e mafai ona faʻaaogaina e fai ma faʻailoga, e foliga samasama ile pH 3.8 ma le lanumoana-lanumeamata ile pH 5.4.
