I-Chromic Acid

Ukuhlaziya indlela yokuhlela

Ukunqunywa kokuqukethwe kwe-chromic acid emoyeni: isampula yaqoqwa ngesihlungi, yancibilika ku-sulfuric acid, bese inqunywa nge-colorimetry ngemva kokwengeza i-diphenylcarbazide (indlela ye-NIOSH).

Ukunqunywa kokuqukethwe kwe-chromic acid emanzini: isampuli ikhishwa futhi inqunywe i-atomic absorption spectrometry noma i-colorimetry.

Indlela yokulahla imfucuza: uketshezi lwemfucumfucu ye-chromic acid egxilile luguqulwa lube i-chromium eyi-trivalent ngemva kokunciphisa amakhemikhali, futhi inani le-pH lesixazululo liyalungiswa ukuze libe imvula, futhi imvula igcwaliswa njengodoti wamakhemikhali.

Ukusebenzisa ukuhlela

I-Chromic acid iwuketshezi lokuhlanza oluvame kakhulu olusetshenziswa elabhorethri.Inakho kokubili i-acidity kanye ne-oxidizability.Ingasusa ukungcola nezinto ezingancibiliki ezindongeni zangaphakathi nezingaphandle zamathuluzi okuhlola.Ngokuvamile, isixazululo sokugeza sitholakala ngokungeza i-potassium dichromate ku-concentrated sulfuric acid, kodwa i-chromium eyi-hexavalent iyingozi emvelweni, futhi ngezinye izikhathi insimbi yonakaliswa endaweni ene-acidic eqinile, ngakho-ke ukusetshenziswa kwe-chromic acid lotion kuye kwancishiswa.

I-Chromic acid ingasetshenziswa njenge-oxidant.Izinhlanganisela eziningi zezinto eziphilayo zingafakwa i-oxidized nge-chromic acid, futhi ama-oxidants amaningi asekelwe ku-chromium ene-hexavalent akhiwe.I-Jones reagent: isixazululo esinamanzi se-chromic acid, i-sulfuric acid, ne-acetone esixilisa uphuzo oludakayo oluyisisekelo nolwesibili kuma-carboxylic acid nama-ketone ahambisanayo ngaphandle kokuthinta izibopho ezingagcwalisiwe.I-Pyridinium chloride chromate: elungiselelwe i-chromium trioxide ne-pyridine hydrochloride, ingakhipha utshwala obuyisisekelo ku-aldehyde.I-Collins reagent: i-adduct ye-chromium trioxide ne-pyridine.

I-Chromic acid ingabuye isetshenziselwe ukucwenga kwe-chromium, i-chromium yensimbi ehlanzekile, i-pigment, i-mordant, imithi kanye nokuthintana namalahle, kanye nokukhiqizwa kwamanye ama-glaze nezingilazi ezinemibala.
