I-sodium bicarbonate, esetshenziswa njengesoda yokubhaka kanye nempushan yokubhaka, iyona evame ukubilisa.Uma i-baking soda, okuwuketshezi olune-alkali, yengezwa kwingxube, ihlangana nesithako esine-asidi ukukhiqiza isikhutha.Ukusabela kungamelwa njengokuthi: NaHCO3(s) + H+ → Na+(aq) + H2O(l) +CO2(g), lapho i-H+ inikezwa i-asidi.Ama-baking powders aqukethe i-baking soda njengesithako esiyinhloko kanye ne-asidi nezinye izithako.Kuye ngokwakhiwa, ama-bakingpowder angakhiqiza i-carbon dioxide ngokushesha njengempushana yesenzo esisodwa noma ngezigaba, njengempushana yesenzo esiphindwe kabili.Isoda yokubhaka iphinde isetshenziswe njengomthombo we-carbon dioxide eziphuzweni ezine-carbonated nanjenge-buffer.Ngaphezu kokubhaka, i-baking soda inokusetshenziswa okuningi ekhaya.Isetshenziswa njengesihlanzi esijwayelekile, isiqedaphunga, i-antacid, into yokucindezela umlilo, nasemikhiqizweni yomuntu siqu efana nomuthi wokuxubha.I-sodium bicarbonate iyisisekelo esibuthakathaka esixazululweni esinamanzi, esine-pH engaba ngu-8. I-Thebicarbonate ion (HCO3-) ine-amphoteric izakhiwo, okusho ukuthi ingasebenza njenge-acid noma isisekelo.Lokhu kunikeza i-baking soda amandla e-ring ye-buff kanye nekhono lokuqeda zombili izisekelo ze-asidi nezisekelo.Amaphunga okudla avela ezinhlanganisela ezine-asidi noma eziyisisekelo angancishiswa nge-bakingsoda abe usawoti ongenaphunga.Ngenxa yokuthi i-sodium bicarbonate iyisisekelo esibuthakathaka, inamandla amakhulu okunciphisa iphunga le-asidi.
Ukusetshenziswa kwesibili okukhulu kwe-sodium bicarbonate, okubalelwa cishe ku-25% wokukhiqiza okuphelele, kuyisithasiselo sokudla kwezolimo.Ezinkomeni isiza ukugcina i-rumen pH futhi isiza ukugaya i-fiber;enkukhu isiza ukugcina ibhalansi ye-electrolyte ngokunikeza i-sodium ekudleni, isiza izinyoni ukuthi zibekezelele ukushisa, futhi ithuthukise ikhwalithi yegobolondo lamaqanda.
I-sodium bicarbonate isetshenziswa embonini yamakhemikhali njenge-buff ring agent, i- blowingagent, i-catalyst, kanye ne-feedstock yamakhemikhali.I-sodium bicarbonate isetshenziswa embonini yesikhumba ukuze kuhlanjululwe futhi kuhlanzwe izikhumba kanye nokulawula i-pH ngesikhathi senqubo yokushuka.I-sodium bicarbonate yokushisa ikhiqiza i-sodium carbonate, esetshenziselwa insipho nokwenza ingilazi.I-sodium bicarbonate ifakwa kwezemithi ukuze isebenze njenge-antacid, i-abuff. i-ering ejenti, nasemikhiqizweni njengomthombo we-carbon dioxide kumaphilisi asebenzayo.Izicishamlilo zohlobo lwe-BC zohlobo lwekhemikhali eyomile ziqukethe i-sodium bicarbonate (noma i-potassium bicarbonate). Okunye ukusetshenziswa kwe-bicarbonate kufaka phakathi ukucutshungulwa kwe-pulp nephepha, ukuhlanzwa kwamanzi, nokubhobolwa kwemithombo kawoyela.
I-Sodium Bicarbonate iyi-ejenti eyenza imvubelo ene-ph ecishe ibe ngu-8.5 kwisisombululo esingu-1% ku-25°c.isebenza nama-phosphates ebanga lokudla (izinhlanganisela ze-acidic imvubelo) ukukhulula isikhutha esikhula ngesikhathi sokubhaka ukuze sinikeze okubhakiwe okuphekiwe ngevolumu eyengeziwe kanye nezimfanelo zokudla ezithambile.ibuye isetshenziselwe eziphuzweni eziyingxube eyomile ukuze kutholwe i-carbonation, okuholela lapho amanzi engezwa kungxube equkethe i-sodium bicarbonate ne-asidi.kuyingxenye ye-baking powder.ibizwa nangokuthi i-baking soda, i-bicarbonate of soda, i-sodium acid carbonate, ne-sodium hydrogen carbonate.
ukukhiqizwa kosawoti abaningi be-sodium;umthombo we-CO2;isithako se-baking powder, usawoti osebenzayo kanye neziphuzo;ezicishamlilo, ukuhlanza ama-Compounds.
i-sodium bicarbonate (i-baking soda) iwusawoti we-inorganic osetshenziswa njenge-ejenti ephazamisayo kanye ne-pH adjuster, iphinde isebenze njenge-neutralizer.Isetshenziselwa izimpushana ezishelela isikhumba.
