Isodium bicarbonate, esetyenziswa kwimo yesoda yokubhaka kunye nomgubo wokubhaka, yeyona arhente ixhaphakileyo yegwele.Xa i-baking soda, eyi-alkaline substance, idityaniswe kumxube, isabela kunye nesithako se-asidi ukuvelisa ikharbon diokside.Ukusabela kunokubonakaliswa njenge: NaHCO3(s) + H+ → Na+(aq) + H2O(l) +CO2(g), apho i-H+ inikezelwa yi-asidi.Umgubo wokubhaka unesoda yokubhaka njengesithako esisisiseko kunye neasidi kunye nezinye izithako.Ngokuxhomekeke ekuqulunqweni, i-bakingpowders inokuvelisa i-carbon dioxide ngokukhawuleza njengepowder yesenzo esisodwa okanye kwizigaba, njenge-powder-action-action.Isoda yokubhaka ikwasetyenziswa njengomthombo wekharbon diokside kwiziselo ezinekhabhoni kunye nanjengesithinteli. Ukongeza kwisoda yokubhaka, i-baking soda inemisebenzi emininzi yasekhaya.Isetyenziswa njenge-generalcleanser, i-deodorizer, i-antacid, i-fire suppressant, kunye neemveliso zomntu ezifana ne-toothpaste.I-bicarbonate ye-sodium sisiseko esibuthathaka kwisisombululo esinamanzi, kunye ne-pH malunga ne-8. I-ion ye-Thebicarbonate (HCO3-) ine-amphoteric iipropathi, okuthetha ukuba inokusebenza njenge-asidi okanye isiseko.Oku kunika i-soda yokubhaka amandla e-ring ye-buff kunye nokukwazi ukunciphisa zombini i-asidi kunye neziseko.Ukuvumba kokutya okuvela kwi-acidic okanye kwi-basic compounds kunokuthi kuthintelwe kunye ne-bakingsoda kwiityuwa ezingenavumba.Ngenxa yokuba i-sodium bicarbonate isisiseko esibuthathaka, inamandla amakhulu okunciphisa amavumba e-asidi.
Olona setyenziso lwesibini lukhulu lwesodium bicarbonate, ebalelwa malunga ne-25% yemveliso iyonke, ifana nesongezo sokutya kwezolimo.Ezinkomeni inceda ukugcina i-rumen i-pH kwaye inceda ukucolwa kwefayibha;kwinkukhu inceda ukugcina ibhalansi ye-electrolyte ngokubonelela ngesodium ekudleni, inceda iintaka zibunyamezele ubushushu, kwaye iphucula umgangatho weqokobhe leqanda.
Isodium bicarbonate isetyenziswa kwishishini lemichiza njenge-ejenti ye-buff ering, i-blowingagent, i-catalyst, kunye ne-feedstock yekhemikhali.Sodium bicarbonate isetyenziswa ngesikhumba tanningindustry for pretreating kunye nokucoca izikhumba kunye nokulawula pH ngexesha tanning process.Heating sodium bicarbonate uvelisa carbonate sodium, esetyenziselwa isepha kunye glassmaking.Sodium bicarbonate idityaniswe amayeza ukuze akhonze njenge antacid, abuff ering, nakwimixube njengomthombo wecarbon dioxide kwiipilisi ezisebenzayo.I-Drychemical type BC izicima-mlilo ziqulethe i-sodium bicarbonate (okanye i-potassium bicarbonate).Olunye usetyenziso lwe-bicarbonate lubandakanya i-pulp kunye nokulungiswa kwephepha, ukucocwa kwamanzi, kunye nokugrunjwa kwe-oyile.
I-Sodium Bicarbonate yi-arhente enegwele ene-ph emalunga ne-8.5 kwisisombululo se-1% kwi-25°c.isebenza kunye ne-phosphates yebakala lokutya (i-acidic igwele ikhompawundi) ukukhulula i-carbon dioxide eyanda ngexesha lenkqubo yokubhaka ukubonelela okulungileyo okubhakiweyo kunye nomthamo owandisiweyo kunye neempawu zokutya ezithambileyo.iphinda isetyenziswe kwiziselo ezixubeneyo ezomileyo ukufumana i-carbonation, ebangela ukuba amanzi afakwe kumxube oqukethe i-sodium bicarbonate kunye ne-asidi.yinxalenye yomgubo wokubhaka.ikwabizwa ngokuba yisoda yokubhaka, ibhicarbonate yesoda, i-sodium acid carbonate, kunye nesodium hydrogen carbonate.
ukwenziwa kweetyuwa ezininzi zesodium;umthombo weCO2;isithako se powder yokubhaka, iityuwa ezivuthayo kunye neziselo;kwizicimi-mlilo, ukucoca Compounds.
i-sodium bicarbonate (isoda yokubhaka) yityuwa ye-inorganic esetyenziswa njenge-agent ephazamisayo kunye nesilungelelaniso se-pH, ikwasebenza njengesithambiso.Isetyenziselwa umgubo wokuthambisa ulusu.
