Waa maxay Bromocresol Cagaare leh CAS 76-60-8?

Cagaarka Bromocresol waa wax yar oo ku milma biyaha wuxuuna ku milmaa ethanol, ether, ethyl acetate, iyo benzene. Aad u xasaasi u ah alkali, cagaarka Bromocresol wuxuu u rogaa midab buluug-cagaaran gaar ah marka uu la kulmo xalalka aqueous alkaline. Cagaarka Bromocresol waxaa loo isticmaali karaa tilmaame ahaan, oo u muuqda huruud pH 3.8 iyo buluug-cagaaran pH 5.4.

Codsiga

1.Bromocresol cagaaran waa wakiilka wasakhaynta unugyada
2.Bromocresol cagaar waa tusaha acid-saldhigga, pH midabka isbeddelka u dhexeeya 3.8 (jaalle) ilaa 5.4 (buluug-cagaaran)
3.Bromocresol milixda cagaarka ah ee sodium waxaa badanaa loo isticmaalaa go'aaminta midabka midabka ee acidity iyo alkalinity. Xalka cusbada sodium ee cagaarka ah ee Bromocresol waxa loo isticmaalaa sidii wakiilka midabaynta si loo cabbiro qiimaha pH ee spectrophotometry. Loo isticmaalo sida reagent ee chromatography lakabka dhuuban si loo go'aamiyo aliphatic hydroxyacids iyo alkaloids, iyo sidii soo saarista iyo wakiilka kala soocida ee go'aaminta sawir-qaadista ee cations ammonium quaternary.
