Calaamadaha Alaabta

Waa maxay Bromocresol Green oo leh CAS 76-60-8?

Cagaarka Bromocresol wuxuu xoogaa ku milmaa biyaha wuxuuna ku milmaa ethanol, ether, ethyl acetate, iyo benzene. Aad ayuu ugu nugul yahay alkali, cagaarka Bromocresol wuxuu isu beddelaa midab buluug-cagaar gaar ah marka uu la kulmo xalal biyood oo alkaline ah. Cagaarka Bromocresol waxaa loo isticmaali karaa tilmaame ahaan, isagoo u muuqda jaalle pH 3.8 iyo buluug-cagaar pH 5.4.

Codsiga

1. Cagaarka Bromocresol waa wakiilka wasakhaynta unugyada
2. Cagaar Bromocresol waa tilmaame saldhig aashito ah, isbeddelka midabka pH wuxuu u dhexeeyaa 3.8 (jaalle) ilaa 5.4 (buluug-cagaar)
3. Cusbo soodhiyam cagaaran oo Bromocresol ah ayaa badanaa loo isticmaalaa go'aaminta midabka aashitada iyo alkalinity. Xalka cusbada soodhiyam ee Bromocresol cagaaran waxaa loo isticmaalaa sidii wakiil midab leh si loo cabbiro qiimaha pH iyadoo la adeegsanayo spectrophotometry. Waxaa loo isticmaalaa sidii reagent-ka lakabka khafiifka ah ee koromagrafiga si loo go'aamiyo hydroxyacids-ka aliphatic iyo alkaloids-ka, iyo sidii wakiil soo saarid iyo kala-soocid ah oo loogu talagalay go'aaminta sawir-qaadista ee cations-ka ammonium-ka ee quaternary.
