Bicarbonate yeSodium | 144-55-8
IiNkcazo zeeMveliso
Isodium bicarbonate ngokwesiseko yikhompawundi yeekhemikhali, ekwaziwa ngokuba yisoda yokubhaka, isoda yesonka, isoda yokupheka kunye nebhikharnate yesoda. Abafundi besayensi kunye nekhemistri bakwathiye i-sodium bicarbonate njenge-sodium bicarb, i-bicarb soda. Ngamanye amaxesha ikwabizwa ngokuba yi-bi-carb. Igama lesiLatini le-sodium bicarbonate yi-Saleratus, elithetha, 'ityuwa enomoya'. Isodium bicarbonate lilungu leminerali yeNatron, ekwabizwa ngokuba yiNahcolite edla ngokufumaneka kwimithombo yeminerali, ekuphela komthombo wendalo wesodium bicarbonate.
Ukupheka ukusetyenziswa: I-sodium bicarbonate yayisetyenziselwa ukupheka imifuno, ukuyenza ibe thambileyo, nangona oku kuphumile efashonini, njengoko abantu abaninzi ngoku bekhetha imifuno eqinile enezondlo ezininzi. Nangona kunjalo, isasetyenziswa kwi-cuisine yase-Asia ukwenza inyama. Isoda yokubhaka inokusabela ngeeasidi ekutyeni, kuquka iVithamin C (L-Ascorbic Acid). Ikwasetyenziswa kwizonka ezinje ngokutya okuqhotsiweyo ukwenza ukuba crispness. Ukubola kwe-thermal kubangela i-sodium bicarbonate iyodwa ukuba isebenze njenge-arhente yokunyusa ngokukhupha i-carbon dioxide kumaqondo obushushu okubhaka. Imveliso yekharbon diokside iqala kumaqondo obushushu angaphezu kwama-80 °C. Umxube wamaqebengwana usebenzisa le ndlela unokuvunyelwa ukuba ume phambi kokubhaka ngaphandle kokukhululwa kwangaphambili kwekharbon diokside.
Ukusetyenziswa kwezonyango: Isodium bicarbonate isetyenziswa kwisisombululo esimanzi njenge antacid ethathwe ngomlomo ukunyanga ukugaywa kweasidi kunye nesitshisa. Isenokusetyenziswa ngendlela yomlomo ukunyanga iindlela ezingapheliyo ze-metabolic acidosis ezifana nokusilela okungapheliyo kweentso kunye ne-acidosis ye-renal tubular. Isodium bicarbonate inokuba luncedo kwialkalinization yomchamo kunyango lwe-aspirin overdose kunye namatye e-uric acid ezintso. Isetyenziswa njengeyeza lokunyanga kumanzi egripe kwiintsana.
