Acid-base titration indicator "Methyl orange inowanzoshandiswa acid-base titration indicator mu analytical chemistry. Yayo 0.1% aqueous solution ine pH ye 3.1 (tsvuku) kusvika 4.4 (yellow). Inokodzera asidhi yakasimba uye yakasimba. base, Titration pakati pezvigadziko zvisina simba.Inowanikwa muchimiro che sulfonic acid sodium munyu mune neutral kana alkaline solution, uye inoshandurwa kuita sulfonic acid mu acidic solution, kuitira kuti acidic sulfonic acid group iumbe nebasic dimethylamino group mumorekuru. Iyo yemukati munyu fomu (paraquinone chimiro) ye-p-dimethylaminophenylazobenzenesulfonic acid inova iyo conjugated system ine p-quinone chimiro, saka ruvara runochinja zvinoenderana, uye harukodzere titration ye organic acid makomisheni Inoshandiswawo kune spectrophotometric kutsunga kweklorini. , bromine uye bromide ions Inoshandiswawo pakudhaya zvipenyu, etc. Methyl orenji yakashandiswa murabhoritari uye muindasitiri uye kurima kugadzirwa kwepH kutonga kwemakemikari kuita uye asidhi yezvigadzirwa zvemakemikari uye yepakati Alkali titration ongororo.Muindasitiri yekudhinda nekudhaya, iyo yakasara pH pamucheka inofanirwa kuyerwa nechiratidzo uye kugezwa kuti jira rive risina divi.Kana jira racho riine acidity, rinokanganisa ruvara uye ruvara kana rakadhayiwa kana kudhindwa nedhayi dzinoshanda.Fastness.Kuipa kwemethyl orange chiratidzo ndechekuti iyo yero-tsvuku ruvara yakanyanya kuoma kuziva, uye iko zvino yakatsiviwa neyakasiyana-siyana yezviratidzo (ona "phenolphthalein").Methyl orange zvakare ndeye azo dhayi, iyo inogona kushandiswa kudhinda uye kudhaya machira.

Zvishandiso: Sechiratidzo cheasidhi-base, pH3.1 (tsvuku) -4.4 (yero), inoshandiswawo pakudhaya zvipenyu.

Zvishandiso: acid-base indicator, pH discoloration inobva ku3.1 (tsvuku) kusvika ku4.4 (yero), kugadziriswa kwealkalinity yeakawanda mineral acids, mabhesi akasimba uye mvura;volumetric kutsunga kwetini (Sn2 + inopera methyl orange kana inopisa);kuderera kwakasimba Decolorizing chiratidzo cheoxidants (Ti3+, Cr2+) uye yakasimba oxidants (chlorine, bromine);spectrophotometric kusarudza kweklorini, bromine uye bromide ions;inogona kusanganiswa ne sodium indigo disulfonate kana bromocresol yegirini kuita chiratidzo chakasanganiswa kupfupisa discoloration Domain uye kuwedzera kupinza kwekushanduka kwemavara;redox zviratidzo zvakadai se trivalent arsenic kana antimony ye potassium bromate titration

Zvishandiso: Acid-base chiratidzo, achromatic chiratidzo chesimba rekudzikisa mumiririri uye yakasimba oxidant, cytoplasmic chiratidzo, histological kusiyanisa tsvina, pollen chubhu staining.Iyo pH kukosha inoshandura ruvara kubva pa 3.1 (tsvuku) kusvika 4.4 (yero), uye inosarudza alkalinity yeakawanda mineral acids, alkali yakasimba uye mvura.Volumetric kutsunga kwetin (Sn2+ discolors methyl orange kana inopisa).Decolorizing chiratidzo chevakasimba kuderedza vamiririri (Ti3+), Cr2+) uye yakasimba oxidizing agents (chlorine, bromine).Spectrophotometric kutsunga kweklorini, bromine uye bromide ion.Inogona kusanganiswa ne sodium indigo disulfonate kana bromocresol yegirini kuti iite chiratidzo chakasanganiswa kupfupisa shanduko yeruvara uye kuvandudza kupinza kwemavara shanduko.Redox zviratidzo zvakadai se trivalent arsenic kana antimony ye potassium bromate titration.
