Chii chinonzi Bromocresol Purple CAS 115-40-2?

Bromocresol Yepepuru hainyungudike mumvura, inonyungudika mu ethanol uye inoita yero, inonyungudika mu dilute sodium hydroxide uye inonatsa sodium carbonate mhinduro uye inoita yepepuru yakatsvuka, iine nzvimbo yekunyungudika ye241-242 ℃. Iko kushandiswa kukuru kwebromocresol violet ndeye acid-base chiratidzo uye isiri-aqueous titration chiratidzo.
