Kugwiritsa ntchito: Methyl orange wakhala akugwiritsidwa ntchito mu labotale ndi mafakitale ndi ulimi kupanga pH kuwongolera kachitidwe ka mankhwala ndi acid-base titration kusanthula kwa mankhwala ndi zapakati.M'makampani osindikizira ndi opaka utoto, pH yotsalira pa nsalu iyenera kuyesedwa ndi chizindikiro ndikutsukidwa kuti nsaluyo isalowerere.Ngati pali asidi pa nsalu ya Chemicalbook, imakhudza mtundu wake komanso kufulumira kwake ikapakidwa utoto kapena kusindikizidwa ndi utoto wokhazikika.Choyipa cha chizindikiro cha methyl orange ndikuti mtundu wofiira wachikasu ndi wovuta kuuzindikira, ndipo tsopano wasinthidwa ndi zizindikiro zambiri.Methyl orange ndi utoto wa azo womwe ungagwiritsidwe ntchito kusindikiza ndi kuyika nsalu

Chizindikiro cha acid-base titration "Methyl orange ndi chizindikiro chodziwika bwino cha acid-base titration mu chemistry yowunikira. Kuphatikizika kwake kwa 0.1% yamadzimadzi kumakhala ndi pH ya 3.1 (yofiira) mpaka 4.4 (yellow). Ndi yoyenera kwa asidi amphamvu komanso amphamvu Base, Titration pakati pa maziko ofooka Imakhala mu mawonekedwe a sulfonic asidi sodium mchere mu ndale kapena zamchere njira, ndipo n'kukhala asidi sulfonic mu acidic njira, kotero kuti acidic sulfonic asidi gulu kupanga ndi zoyambira dimethylamino gulu mu molekyulu. Mchere wamchere wamkati (paraquinone dongosolo) wa p-dimethylaminophenylazobenzenesulfonic acid umakhala conjugated system yomwe ili ndi p-quinone, motero mtunduwo umasintha molingana, ndipo siwoyenera kuti titration wa mankhwala a organic acid Amagwiritsidwanso ntchito pozindikira chlorine. Amagwiritsidwanso ntchito popaka utoto wachilengedwe, etc. Methyl lalanje yakhala ikugwiritsidwa ntchito mu labotale ndi mafakitale ndi ulimi kupanga pH kuwongolera machitidwe amankhwala ndi asidi pakupanga mankhwala ndi intermediates Alkali titration kusanthula.M'makampani osindikizira ndi opaka utoto, pH yotsalira pa nsalu iyenera kuyesedwa ndi chizindikiro ndikutsukidwa kuti nsaluyo isalowerere.Ngati nsaluyo ili ndi acidity, imakhudza mtundu wake ndi mtundu wake ikapakidwa utoto kapena kusindikizidwa ndi utoto wokhazikika.Kuthamanga.Kuipa kwa chizindikiro cha methyl orange ndikuti mtundu wofiyira wachikasu ndi wovuta kuuzindikira, ndipo tsopano wasinthidwa ndi zizindikiro zambiri (onani "phenolphthalein").Methyl lalanje ndi utoto wa azo, womwe ungagwiritsidwe ntchito kusindikiza ndi kudaya nsalu.

Ntchito: Monga chizindikiro cha acid-base, pH3.1 (red) -4.4 (yellow), imagwiritsidwanso ntchito podaya zamoyo.

Zogwiritsira ntchito: chizindikiro cha acid-base, pH kusinthika kwamtundu kuchokera ku 3.1 (yofiira) mpaka 4.4 (chikasu), kutsimikiza kwa alkalinity ya mchere wambiri wa mchere, maziko amphamvu ndi madzi;kutsimikiza kwa voliyumu ya malata (Sn2 + imazirala methyl lalanje ikatenthedwa);kuchepetsa kwambiri Decolorizing chizindikiro cha okosijeni (Ti3+, Cr2+) ndi oxidants amphamvu (klorini, bromine);spectrophotometric kutsimikiza kwa klorini, bromine ndi bromide ayoni;imatha kuphatikizidwa ndi sodium indigo disulfonate kapena bromocresol wobiriwira kupanga chizindikiro chosakanikirana kuti chifupikitse kusinthika kwa Domain ndikuwonjezera kuthwa kwa kusintha kwamtundu;zizindikiro za redox monga trivalent arsenic kapena antimoni ya potaziyamu bromate titration

Ntchito: Chizindikiro cha Acid-base, chizindikiro cha achromatic cha achromatic reduction agent ndi oxidant amphamvu, chizindikiro cha cytoplasmic, banga la histological kusiyana, madontho a mungu.Mtengo wa pH umasintha mtundu kuchokera ku 3.1 (wofiira) mpaka 4.4 (wachikasu), ndipo umatsimikizira kuchuluka kwa mchere wa mchere wambiri, alkalis wamphamvu ndi madzi.Kutsimikiza kwa volumetric ya malata (Sn2+ discolors methyl lalanje pakatentha).Chizindikiro cha decolorizing cha ochepetsa amphamvu (Ti3+), Cr2+) ndi ma oxidizing amphamvu (chlorine, bromine).Kutsimikiza kwa Spectrophotometric kwa chlorine, bromine ndi ayoni a bromide.Ikhoza kuphatikizidwa ndi sodium indigo disulfonate kapena bromocresol wobiriwira kuti apange chizindikiro chosakanikirana kuti chifupikitse kusintha kwa mtundu ndikusintha kusintha kwamtundu.Zizindikiro za redox monga trivalent arsenic kapena antimoni ya potaziyamu bromate titration.
