Alaabta

Codsiga: Methyl orange ayaa loo adeegsaday shaybaadhka iyo warshadaha iyo wax soo saarka beeraha ee xakamaynta pH ee falcelinta kiimikada iyo falanqaynta titration acid-saldhigga ee alaabta kiimikada iyo dhexdhexaadiyeyaasha.Warshadaha daabacaadda iyo midabaynta, pH-ga ku haray dharka waa in lagu cabbiraa tilmaame oo la dhaqo si dharka looga dhigo mid dhexdhexaad ah.Haddii aysiidh ku jirto marada buug-yaraha ee Kiimikada, waxay saamayn doontaa midabkeeda iyo xajinteeda marka la midabeeyo ama lagu daabaco midabyo fal-celin leh.Khasaaraha tilmaame orange methyl waa in midabka huruud-cas ay aad u adag tahay in la aqoonsado, waxaana hadda lagu beddelay tilmaameyaal kala duwan.Methyl orange sidoo kale waa dheeha azo ah oo loo isticmaali karo daabacaadda iyo rinjiyeynta dunta

Tilmaamaha titration acid-saldhigga "Methyl orange waa tilmaame titration ah oo caadi ahaan loo isticmaalo ee kimistari gorfaynta. Its fiirsashada 0.1% xal aqueous leeyahay pH of 3.1 (cas) ilaa 4.4 (jaalle ah). Waxay ku haboon acid xoog leh iyo xoog Saldhig, Titration dhexeeya saldhigyada daciifka ah.Waxay u jirtaa qaab cusbada sulfonic acid sodium ee dhexdhexaad ah ama xalalka alkaline, waxaana loo beddelaa sulfonic acid ee xal acidic, si ay kooxda acidic sulfonic acid ay la sameeyaan kooxda aasaasiga ah ee dimethylamino ee molecule. Qaabka milixda gudaha (qaab dhismeedka paraquinone) ee p-dimethylaminophenylazobenzenesulfonic acid wuxuu noqdaa nidaam isku dhafan oo ka kooban qaab-dhismeedka p-quinone, markaa midabku wuu isbeddelaa si waafaqsan, oo kuma habboona titration of xeryahooda acid organic Waxa kale oo loo isticmaalaa go'aaminta spectrophotometric ee chlorine. .Warshadaha daabacaadda iyo midabaynta, pH-ga haraaga ah ee dharka waa in lagu cabbiraa tilmaame oo la dhaqo si dharka looga dhigo dhexdhexaad.Haddii maradu aysiidh leedahay, waxay saamaynaysaa midabkeeda iyo midabkeeda marka la midabeeyo ama lagu daabaco midabyo fal-celin leh.Degdegga.Khasaaraha tusaha orange-ka methyl waa in midabka huruudda-cas uu aad u adag yahay in la aqoonsado, waxaana hadda lagu beddelay tilmaameyaal kala duwan (eeg "phenolphthalein").Methyl orange sidoo kale waa dheeha azo, kaas oo loo isticmaali karo daabacaadda iyo midabaynta dunta.

Isticmaala: Tilmaame-saldhig-acid, pH3.1 (casaan) -4.4 (jaalle), oo sidoo kale loo isticmaalo dheehaynta noolaha.

Waxay isticmaashaa: tusaha acid-saldhigga, midabka pH wuxuu u dhexeeyaa 3.1 (casaan) ilaa 4.4 (jaalle), go'aaminta alkalinity ee inta badan asiidhyada macdanta, saldhigyada xooggan iyo biyaha;go'aaminta mugga ee daasadaha (Sn2+ waxay luminaysaa methyl orange marka la kululeeyo);hoos u dhac xoog leh Tilmaamaha midabaynta ee oksaydhiyeyaasha (Ti3+, Cr2+) iyo oksaydhiyeyaasha xooggan (chlorine, bromine);spectrophotometric go'aaminta chlorine, bromine iyo bromide ions;waxaa lagu dari karaa sodium indigo disulfonate ama bromocresol cagaar si ay u sameeyaan tilmaame isku dhafan si loo gaabiyo Domain midabka iyo kor loogu qaado fiiqan ee isbedelka midabka;tilmaamayaasha redox sida trivalent arsenic ama antimony ee titration bromate ee potassium

Wuxuu adeegsadaa: tusiyaha acid-saldhigga, tusaha achromatic ee wakiilka yaraynta xooggan iyo oksaydhiyeyaasha xooggan, tusaha cytoplasmic, wasakh ka duwanaanshaha taariikhiga ah, wasakhaynta tuubada manka.Qiimaha pH-ku wuxuu isbeddelaa inta u dhaxaysa 3.1 (casaan) ilaa 4.4 (jaalle), waxayna go'aamisaa alkalinity ee inta badan asiidhyada macdanta, alkalis xooggan iyo biyaha.Go'aaminta mugga cabbirka ee daasadda (Sn2+ waxay midabaysaa methyl orange marka uu kulul yahay).Tilmaamaha midabaynta ee wakiilada yaraynta xooggan (Ti3+), Cr2+) iyo wakiilada oksaydhiyeyaasha xooggan (chlorine, bromine).Go'aaminta Spectrophotometric ee chlorine, bromine iyo ion bromide.Waxaa lagu dari karaa sodium indigo disulfonate ama bromocresol cagaar si ay u sameeyaan tilmaame isku dhafan si loo yareeyo kala duwanaanshaha isbeddelka midabka iyo hagaajinta fiiqan ee isbeddelka midabka.Tilmaamayaasha Redox sida trivalent arsenic ama antimony ee titration bromate ee potassium.
