Isicelo: I-Methyl orange isetyenziswe kwilabhoratri kunye nemveliso yezolimo kunye nemveliso ye-pH yokulawulwa kweekhemikhali kunye nohlalutyo lwe-acid-base titration yeemveliso zekhemikhali kunye neziphakathi.Kwishishini lokuprinta kunye nokudaya, i-pH eseleyo kwilaphu kufuneka ilinganiswe ngesalathisi kwaye ihlanjwe ukuze i-laphu ingathathi hlangothi.Ukuba kukho iasidi kwilaphu leziqhamo zeChemicalbook, iyakuchaphazela umbala wayo kunye nokukhawuleza kwayo xa idayiwe okanye iprintwa ngeedayi ezisebenzayo.Ukungalungi kwesalathisi se-methyl orange kukuba umbala ophuzi obomvu unzima kakhulu ukuchonga, kwaye ngoku utshintshile uluhlu olubanzi lwezibonakaliso.I-Methyl orange ikwayidayi ye-azo enokuthi isetyenziswe ukuprinta kunye nokudaya impahla
Isalathisi se-Acid-base titration "I-Methyl i-orange isetyenziswa ngokuqhelekileyo isalathisi se-acid-base titration kwi-chemistry yohlalutyo. I-concentration yayo ye-0.1% yesisombululo se-aqueous ine-pH ye-3.1 (ebomvu) ukuya kwi-4.4 (ephuzi). Ifanelekile i-asidi eqinile kunye neyomelele. isiseko, i-Titration phakathi kweziseko ezibuthathaka.Ikhona kwifom ye-sulfonic acid yetyuwa yesodium kwisisombululo esingathathi hlangothi okanye se-alkaline, kwaye iguqulwa ibe yi-sulfonic acid kwisisombululo esine-acidic, ukwenzela ukuba iqela le-acidic sulfonic acid lenze kunye neqela elisisiseko le-dimethylamino kwi-molecule. Ifomu yetyuwa yangaphakathi (isakhiwo se-paraquinone) ye-p-dimethylaminophenylazobenzenesulfonic acid iba yinkqubo edibeneyo equlethe isakhiwo se-p-quinone, ngoko umbala utshintsha ngokufanelekileyo, kwaye ayifanelekanga ukuxutywa kwe-organic acid compounds Ikwasetyenziselwa ukuzimisela kwe-spectrophotometric yeklorine. I-bromine kunye ne-bromide ion Ikwasetyenziselwa ukudaya kwebhayoloji, njl. njl.Kwishishini lokuprinta kunye nokudaya, i-pH eseleyo kwilaphu kufuneka ilinganiswe ngesalathisi kwaye ihlanjwe ukuze i-laphu ingathathi hlangothi.Ukuba ilaphu lineasidi, liya kuchaphazela umbala walo kunye nombala walo xa lidayiwe okanye liprintwe ngeedayi ezisebenzayo.Ukukhawuleza.Ukungalungi kwesalathisi se-methyl orange kukuba umbala ophuzi obomvu unzima kakhulu ukuchonga, kwaye ngoku utshintshile uluhlu olubanzi lwezibonakaliso (bona "phenolphthalein").I-Methyl orange ikwayidayi ye-azo, enokusetyenziselwa ukuprinta kunye nokudaya amalaphu.
Usetyenziso: Njengesalathisi se-asidi, i-pH3.1 (ebomvu) -4.4 (etyheli), ikwasetyenziselwa ukudaya kwebhayoloji.
Ukusetyenziswa: isalathisi se-acid-base, i-pH ye-discoloration isuka kwi-3.1 (obomvu) ukuya kwi-4.4 (ephuzi), ukuzimisela kwe-alkalinity yee-acids ezininzi zamaminerali, iziseko ezinamandla kunye namanzi;ukuzimisela umthamo we-tin (i-Sn2 + iyancipha i-methyl orange xa ishushu);ukunciphisa ngamandla Isalathisi se-Decolorizing kwii-oxidants (Ti3 +, Cr2 +) kunye nee-oxidants ezinamandla (i-chlorine, i-bromine);ukuzimisela kwe-spectrophotometric ye-chlorine, i-bromine kunye ne-bromide ions;inokudibaniswa ne-sodium indigo disulfonate okanye i-bromocresol eluhlaza ukwenza isalathisi esixubileyo sokunciphisa i-Domain discoloration kunye nokwandisa ubukhali bokutshintsha kombala;Iimpawu ze-redox ezifana ne-trivalent arsenic okanye i-antimony ye-potassium bromate titration
Ukusetyenziswa: Isalathisi se-Acid-base, isalathisi se-achromatic ye-agent yokunciphisa eyomeleleyo kunye ne-oxidant enamandla, isalathisi se-cytoplasmic, i-histological difference stain, i-pollen tube staining.Ixabiso le-pH litshintsha umbala ukusuka kwi-3.1 (obomvu) ukuya kwi-4.4 (ephuzi), kwaye imisela i-alkalinity yee-acids ezininzi zamaminerali, i-alkali enamandla kunye namanzi.Ukuzimisela kwe-Volumetric ye-tin (i-Sn2 + i-discolors i-methyl orange xa ishushu).Isalathisi sokunciphisa umbala kwii-agent zokunciphisa ezinamandla (Ti3 +), i-Cr2 +) kunye ne-oxidizing agents ezinamandla (i-chlorine, i-bromine).Ukuzimisela kwe-Spectrophotometric ye-chlorine, i-bromine kunye ne-bromide ions.Inokudibaniswa ne-sodium indigo disulfonate okanye i-bromocresol eluhlaza ukwenza isalathisi esixutywe ukunciphisa uluhlu lokutshintsha umbala kunye nokuphucula ubukhali bokutshintsha kombala.Iimpawu zeRedox ezifana ne-trivalent arsenic okanye i-antimony ye-potassium bromate titration.
