Chromic acid

Ndezi usoro nyocha

Mkpebi nke ọdịnaya chromic acid na ikuku: a na-anakọta ihe nlele ahụ site na nzacha, gbazere na sulfuric acid, wee kpebie site na colorimetry mgbe agbakwunyere diphenylcarbazide (usoro NIOSH).

Mkpebi nke ọdịnaya chromic acid n'ime mmiri: a na-ewepụta ihe nlele ahụ wee kpebisie ike site na nleba anya absorption spectrometry ma ọ bụ colorimetry.

Usoro mkpofu mkpofu: a na-atụgharị mmiri mkpofu chromic acid gbadoro anya ka ọ bụrụ chromium trivalent mgbe mbelata kemịkalụ gasịrị, a na-edozi uru pH nke ngwọta ahụ ka ọ bụrụ mkpọda, a na-ejukwa mmiri mmiri ahụ dị ka mkpofu kemịkal.

Ndozi ojiji

Chromic acid bụ mmiri ọcha a na-ejikarị eme ihe n'ụlọ nyocha.Ọ nwere ma acidity na oxidizability.Ọ nwere ike wepụ unyi na ihe ndị na-adịghị edozi ahụ site na mgbidi dị n'ime na n'èzí nke ngwá ọrụ nnwale.Ọtụtụ mgbe, a na-enweta ihe ngwọta nke ịsacha ahụ site n'ịgbakwunye potassium dichromate n'ime sulfuric acid na-etinye uche, ma chromium hexavalent na-emerụ gburugburu ebe obibi, na mgbe ụfọdụ ngwá ọrụ na-emebi na gburugburu acidic siri ike, n'ihi ya, a na-ebelata ngwa ngwa nke chromic acid lotion.

Enwere ike iji chromic acid dị ka oxidant.Ọtụtụ ogige organic nwere ike oxidized site chromic acid, na ọtụtụ oxidants dabeere na hexavalent chromium e mepụtara.Jones reagent: ihe ngwọta mmiri nke chromic acid, sulfuric acid, na acetone nke na-eme ka mmanya ndị bụ isi na nke abụọ na-adaba na carboxylic acid na ketones na-enweghị emetụta agbụ ndị na-enweghị isi.Pyridinium chloride chromate: nke chromium trioxide na pyridine hydrochloride kwadoro, ọ nwere ike oxidize mmanya mbụ na aldehyde.Collins reagent: ntinye nke chromium trioxide na pyridine.

A pụkwara iji Chromic acid mee ihe maka plating chromium, chromium metal dị ọcha dị elu, pigmenti, mordant, ọgwụ na kọntaktị coal, na mmepụta nke ụfọdụ glazes na iko ndị nwere agba.
