I-Sodium Bicarbonate |144-55-8
Incazelo Yemikhiqizo
I-sodium bicarbonate ngokuyisisekelo iyinhlanganisela yamakhemikhali, eyaziwa nangokuthi i-baking soda, i-bread soda, i-soda yokupheka kanye ne-bicarbonate of soda.Abafundi besayensi namakhemikhali baphinde baqamba i-sodium bicarbonate ngokuthi i-sodium bicarb, i-bicarb soda.Kwesinye isikhathi kubuye kwaziwe nje ngokuthi yi-bi-carb.Igama lesiLatini le-sodium bicarbonate lithi Saleratus, okusho ukuthi, 'usawoti ofakwe umoya'.I-sodium bicarbonate iyingxenye ye-mineral Natron, eyaziwa nangokuthi i-Nahcolite evame ukutholakala emithonjeni yamaminerali, okuwukuphela komthombo wemvelo we-sodium bicarbonate.
Ukusetshenziswa kokupheka: I-sodium bicarbonate ngezinye izikhathi yayisetshenziswa ekuphekeni imifino, ukuze ithambile, nakuba lokhu sekuphumile emfashinini, njengoba abantu abaningi manje sebethanda imifino eqinile equkethe imisoco eyengeziwe.Nokho, isasetshenziswa e-Asian cuisine ukwenza ithenda inyama.Isoda yokubhaka ingase isabele nama-acids ekudleni, okuhlanganisa uVithamini C (L-Ascorbic Acid).Ibuye isetshenziselwe ukwenza isinkwa njengokudla okuthosiwe ukuze kuthuthukiswe ubucwebe.Ukubola okushisayo kubangela i-sodium bicarbonate iyodwa ukuthi isebenze njenge-ejenti ekhuphulayo ngokukhipha isikhutha emazingeni okushisa okubhaka.Ukukhiqizwa kwe-carbon dioxide kuqala emazingeni okushisa angaphezu kuka-80 °C.Ingxube yamaqebelengwane asebenzisa le ndlela ingavunyelwa ukuba ime ngaphambi kokubhaka ngaphandle kokukhululwa kwe-carbon dioxide ngaphambi kwesikhathi.
Ukusetshenziswa kwezokwelapha: I-sodium bicarbonate isetshenziswa kwisisombululo esinamanzi njenge-antacid ethathwe ngomlomo ukwelapha ukungagayeki kwe-asidi nesilungulela.Ingase futhi isetshenziswe ngendlela yomlomo ukwelapha izinhlobo ezingamahlalakhona ze-acidosis ye-metabolic njengokwehluleka kwezinso okungapheli kanye ne-renal tubular acidosis.I-sodium bicarbonate ingase futhi ibe usizo ekwakhiweni komchamo ekwelapheni ukweqisa kwe-aspirin kanye namatshe e-uric acid ezinso.Isetshenziswa njengesithako somuthi emanzini e-gripe ezinganeni.
