Imikhiqizo

Isicelo: I-Methyl orange isetshenziswe elabhorethri kanye nokukhiqizwa kwezimboni kanye nezolimo ukulawula i-pH yokusabela kwamakhemikhali kanye nokuhlaziywa kwe-acid-base titration yemikhiqizo yamakhemikhali kanye nokuphakathi.Embonini yokunyathelisa nokudaya, i-pH esele endwangu kufanele ikalwe ngenkomba futhi igezwe ukuze indwangu ingathathi hlangothi.Uma kune-acidity engutsheni yezithelo ye-Chemicalbook, izothinta umbala wayo nokushesha kwayo lapho idayiwe noma iphrintwa ngodayi abasebenzayo.Ububi benkomba ye-methyl orange ukuthi umbala ophuzi obomvu kunzima kakhulu ukuwubona, futhi manje usuthathelwe indawo yizinhlobonhlobo zezinkomba.I-Methyl orange nayo ingudayi we-azo ongasetshenziselwa ukuphrinta nokudaya izindwangu

Inkomba ye-acid-base titration "I-Methyl orange iyinkomba ye-acid-base titration evame ukusetshenziswa kukhemikhali yokuhlaziya. Ukugxila kwayo kwesisombululo se-aqueous esingu-0.1% kune-pH engu-3.1 (bomvu) kuya ku-4.4 (ephuzi). Ifaneleka i-asidi eqinile futhi enamandla isisekelo, i-Titration phakathi kwezisekelo ezibuthakathaka Ikhona ngesimo sikasawoti we-sulfonic acid sodium kusisombululo esingathathi hlangothi noma se-alkaline, futhi iguqulwa ibe i-sulfonic acid esisombululo esine-asidi, ukuze iqembu le-acidic sulfonic acid lakhe neqembu eliyisisekelo le-dimethylamino ku-molecule. Ifomu likasawoti wangaphakathi (isakhiwo se-paraquinone) se-p-dimethylaminophenylazobenzenesulfonic acid iba isistimu ehlanganisiwe equkethe isakhiwo se-p-quinone, ngakho umbala ushintsha ngokufanele, futhi awufaneleki ukuguqulwa kwe-organic acid compounds Ibuye isetshenziselwe ukunqunywa kwe-spectrophotometric ye-chlorine. , i-bromine ne-bromide ions. Iphinde isetshenziselwe ukudaya izinto eziphilayo, njll. I-Methyl orange isetshenziswe elabhorethri kanye nokukhiqizwa kwezimboni nezolimo ukuze kulawulwe i-pH yokusabela kwamakhemikhali kanye ne-asidi emikhiqizweni yamakhemikhali kanye nokuhlaziywa kwe-alkali titration.Embonini yokunyathelisa nokudaya, i-pH esele endwangu kufanele ilinganiswe nenkomba futhi igezwe ukuze indwangu ingathathi hlangothi.Uma indwangu ine-acidity, izothinta umbala nombala wayo lapho idayiwe noma iphrintiwe ngamadayi asebenzayo.Ukushesha.Ububi benkomba ye-methyl orange ukuthi umbala ophuzi obomvu kunzima kakhulu ukuwubona, futhi manje usuthathelwe indawo yizinkomba eziningi (bona "phenolphthalein").I-Methyl orange nayo ingudayi we-azo, ongasetshenziselwa ukuphrinta nokudaya izindwangu.

Ukusetshenziswa: Njengenkomba ye-acid-base, i-pH3.1 (ebomvu) -4.4 (ephuzi), iphinde isetshenziselwe ukudaya kwebhayoloji.

Ukusetshenziswa: inkomba ye-acid-base, i-pH yokushintsha umbala isuka ku-3.1 (ebomvu) iye ku-4.4 (ophuzi), ukunqunywa kwe-alkalinity yama-acid amaningi amaminerali, izisekelo ezinamandla namanzi;ukunqunywa kwe-volumetric yethini (i-Sn2+ iqeda i-methyl orange uma ishisa);ukuncipha okuqinile Inkomba ye-Decolorizing yama-oxidants (Ti3+, Cr2+) nama-oxidants aqinile (i-chlorine, i-bromine);ukunqunywa kwe-spectrophotometric ye-chlorine, i-bromine ne-bromide ions;ingahlanganiswa ne-sodium indigo disulfonate noma i-bromocresol eluhlaza ukwenza inkomba exubile ukuze kufinyezwe isizinda sokushintsha umbala futhi kuthuthukise ukucijile kokushintsha kombala;izinkomba ze-redox ezifana ne-trivalent arsenic noma i-antimony ye-potassium bromate titration

Ukusetshenziswa: Inkomba ye-Acid-base, inkomba ye-achromatic ye-ejenti yokunciphisa eqinile ne-oxidant eqinile, inkomba ye-cytoplasmic, ibala elihlukile le-histological, i-pollen tube staining.Inani le-pH lishintsha umbala ukusuka ku-3.1 (obomvu) uye ku-4.4 (ophuzi), futhi linquma i-alkalinity yama-acid amaningi amaminerali, ama-alkali aqinile namanzi.Ukunqunywa kwe-volumetric kathayela (i-Sn2+ ihlukanisa i-methyl orange uma kushisa).Inkomba ye-Decolorizing ye-ejenti yokunciphisa eqinile (Ti3+), i-Cr2+) nama-oxidizing agents aqinile (i-chlorine, i-bromine).Ukunqunywa kwe-Spectrophotometric ye-chlorine, i-bromine ne-bromide ions.Ingahlanganiswa ne-sodium indigo disulfonate noma i-bromocresol eluhlaza ukuze yakhe inkomba exubile ukuze ifinyeze ububanzi bokushintshwa kombala futhi ithuthukise ukucijile kokushintsha kombala.Izinkomba ze-Redox ezifana ne-trivalent arsenic noma i-antimony ye-potassium bromate titration.
