Ukusetyenziswa
I-oxalic acidisisombululo esiqhelekileyo sisisombululo se-oxalic acid esinomlinganiselo ochanekileyo owaziwayo kwaye sisetyenziswa kakhulu kwiinkalo ezifana nohlalutyo lweekhemikhali, imveliso yemizi-mveliso, kunye nophando lwesayensi. Iindlela eziphambili zokusetyenziswa zezi zilandelayo:
Uhlalutyo lweeKhemikhali kunye nokuMiselwa
- I-Acid - Base Titration: I-Oxalic acid yi-dibasic weak acid enokuthi ifumane i-neutralization reaction kunye ne-bases. Ingasetyenziswa njengesisombululo se-asidi esiqhelekileyo ukumisela uxinzelelo lwesisombululo se-alkaline esingaziwayo. Umzekelo, xa kutsalwa isisombululo se-sodium hydroxide ngesisombululo se-oxalic acid esiqhelekileyo, kusetyenziswa i-phenolphthalein njengesalathisi, uxinzelelo oluchanekileyo lwesisombululo se-sodium hydroxide lunokubalwa ngokusekelwe kubudlelwane be-stoichiometric kunye nobungakanani besisombululo se-oxalic acid esiqhelekileyo esisetyenziswa ekupheleni kwe-titration.
- I-Redox Titration: I-element yekhabhoni kwi-oxalic acid ine-valence ye-+3, ebonisa ukuncitshiswa kwaye iyakwazi ukusabela nezinto ezinamandla ze-oxidizing kwi-redox reaction. Kwi-acidic medium, i-sodium oxalate inoku-oxidized yi-potassium permanganate. Ukusebenzisa le reaction, isisombululo esisemgangathweni se-oxalic acid singasetyenziselwa ukulinganisa uxinzelelo oluchanekileyo lwesisombululo se-potassium permanganate.
Ulawulo loMgangatho weShishini
- Unyango Lomphezulu Wesinyithi: Kwiinkqubo zokulungisa umphezulu wesinyithi ezifana ne-aluminium, izisombululo ze-oxalic acid zingasetyenziselwa ukukrola nokucoca. Ngokusebenzisa isisombululo esisemgangathweni se-oxalic acid, uxinano lwesisombululo lungalawulwa ngokuchanekileyo ukuqinisekisa ukuhambelana kunye nokuzinza kwesiphumo sonyango lomphezulu wesinyithi, ngaloo ndlela kuphuculwe umgangatho wemveliso. Umzekelo, ngokulawula uxinano lwesisombululo esisemgangathweni se-oxalic acid ngaphakathi koluhlu oluthile, imveliso ye-aluminium ingakrolwa ukuze kufunyanwe ubume obufanayo nobubuhle bomphezulu.
- Ishishini lokuGqibezela nge-Electroplating: Isisombululo esisemgangathweni se-oxalic acid singasetyenziselwa ukulungisa i-acidity kunye nokwakheka kwesisombululo sokuGqibezela nge-electroplating, ukuqinisekisa umgangatho kunye nokusebenza komaleko ogqunywe nge-electroplated. Ukulawula ngokuchanekileyo uxinano lwe-oxalic acid kunceda ukuphucula ukunamathela, ukuqaqamba, kunye nokumelana nokugqwala komaleko ogqunywe nge-electroplated, ukuqinisekisa ukuba iimveliso ezigqunywe nge-electroplated ziyahlangabezana nemigangatho yomgangatho.
Ukupakishwa kunye nokuthunyelwa
