Ukusetshenziswa
I-oxalic acidIsixazululo esijwayelekile siyisisombululo se-oxalic acid esinokuqukethwe okunembile okwaziwayo futhi sisetshenziswa kabanzi emikhakheni efana nokuhlaziywa kwamakhemikhali, ukukhiqizwa kwezimboni, kanye nocwaningo lwesayensi. Izindlela eziyinhloko zokusebenzisa yilezi ezilandelayo:
Ukuhlaziywa Kwamakhemikhali Nokunqunywa
- I-Acid - Base Titration: I-Oxalic acid iyi-dibasic weak acid engabhekana nokusabela kokungathathi hlangothi ngezisekelo. Ingasetshenziswa njengesixazululo se-asidi esijwayelekile ukunquma ukuhlushwa kwesisombululo se-alkaline esingaziwa. Isibonelo, lapho kufakwa isixazululo se-sodium hydroxide ngesisombululo se-oxalic acid esijwayelekile, kusetshenziswa i-phenolphthalein njengenkomba, ukuhlushwa okunembile kwesisombululo se-sodium hydroxide kungabalwa ngokusekelwe ebuhlotsheni be-stoichiometric kanye nenani lesisombululo se-oxalic acid esijwayelekile esisetshenziswa ekugcineni kwe-titration.
- I-Redox Titration: I-carbon element ku-oxalic acid ine-valence engu-+3, ekhombisa ukuncishiswa futhi ikwazi ukusabela nezinto ezinamandla ze-oxidizing ku-redox reaction. Endaweni ene-acidic, i-sodium oxalate ingafakwa i-oxidized yi-potassium permanganate. Kusetshenziswa lokhu kusabela, isixazululo esijwayelekile se-oxalic acid singasetshenziswa ukwenza kube sezingeni elifanele ukuhlushwa kwesisombululo se-potassium permanganate.
Ukulawulwa Kwekhwalithi Yezimboni
- Ukwelashwa Komphezulu Wensimbi: Ezinqubweni zokwelashwa komphezulu wezinsimbi ezifana ne-aluminium, izixazululo ze-oxalic acid zingasetshenziswa ekuqopheni nasekuhlanzeni. Ngokusebenzisa isisombululo esijwayelekile se-oxalic acid, ukuhlushwa kwesisombululo kungalawulwa ngokunembile ukuqinisekisa ukuhambisana nokuqina komphumela wokwelashwa komphezulu wensimbi, ngaleyo ndlela kuthuthukiswe ikhwalithi yomkhiqizo. Isibonelo, ngokulawula ukuhlushwa kwesisombululo esijwayelekile se-oxalic acid ngaphakathi kobubanzi obuthile, umkhiqizo we-aluminium ungaqoshwa ukuze kutholakale ukuthungwa komphezulu okufanayo nokuhle.
- Imboni Yokugoqa Nge-Electroplating: Isixazululo esijwayelekile se-oxalic acid singasetshenziswa ukulungisa i-acidity kanye nokwakheka kwesisombululo se-electroplating, ukuqinisekisa ikhwalithi kanye nokusebenza kwesendlalelo esigoqelwe nge-electroplated. Ukulawula ngokunembile ukugcwala kwe-oxalic acid kusiza ekuthuthukiseni ukunamathela, ukucwebezela, kanye nokumelana nokugqwala kwesendlalelo esigoqelwe nge-electroplated, ukuqinisekisa ukuthi imikhiqizo egoqelwe nge-electroplated ihlangabezana nezindinganiso zekhwalithi.
Ukupakisha Nokuthumela
25KG/Isigubhu noma ngokwezidingo zamakhasimende.
Ukuthunyelwa: Izinhlobo ezi-6 zezimpahla eziyingozi futhi zingathunyelwa olwandle.
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Indawo yokugcina izinto enomoya, Ukomisa okuphansi kwezinga lokushisa, Ihlukaniswe nama-oxidants, ama-acid.
