Inkcazo emfutshane:

I-sodium Bicarbonate, eyindawo ebizwa ngokuba yi-back soda, ikhona njenge-white, engenakuthelekiswa, i-odorstalline. Ivela ngokwendalo njengeminerali yaseNahrali, esuka kwi-formula yayo ngokutshintsha i- "3" eNahco3 enesiphelo "." Umthombo ophambili wehlabathi weNahpisite yi-picey creek salin kwi-Western Colorado, eyinxalenye yomongo omkhulu womthi. I-sodium Bicarbonate ikhutshiwe kusetyenziswa isisombululo sokugovo ngokupeyinta amanzi ashushu ngokunyibilikisa i-nahliniter ye-nahcelite ivela kwi-Oo-1,500 yeenyawo ezingama-2,5,000 ngaphantsi komphezulu. I-sodium yesodium bicarbonate iphoswa kumphezulu apho inyangwa ukuba iphinde ibuyele iNahco3 ukusuka kwisisombululo. I-sodium Bicarbonate inokuveliswa kwakhona kwidipozithi yeTrona, engumthombo we-sodium carcedotes (jonga isodium carbonate).

Iipropathi zeekhemikhali: I-Sodium Bicarbonate, i-Nahc03, ekwabizwa ngokuba yiSodium Acid Carbonate kunye neSoda ye-Alkaline eqinileyo, ilahlekile i-Alkaline Diogide nge-270 ° C) .Isetyenziswa ngaphakathi Ukulungiswa kokutya. I-sodium Bicarbonate ifumana ukusetyenziswa njengeyeza, ibhotile ilondoloze ibhotolo, kwi-ceramics, kunye nokuthintela i-timbers.

Izicelo ze-sodium bicarbonate

I-1. I-Sodium Bicarbonate, isetyenziswe kwi-SODA YOKUZIPHATHA KAKHULU NOKUZIPHATHA NGOKUGQIBELA, yeyona ndoda ixhaphakileyo. Xa i-soda yokubhaka, eyinto engu-alkaline, yongezwa kumxube, iphendula nge-acid ye-acid ukuya kwiDiOXID Daioxide. Impendulo inokumelwa njenge: i-nahco3 (s) + → i-NA + (AQ) + H2O (L) + apho i-HO + ibonelelwa nge-acid. Iipowders ezibhaka ziqukethe isoda yokubhaka njengeyona nto iphambili kunye ne-acid kunye nezinye izithako. Kuxhomekeka ekusetyenzisweni, abasemzimbeni banokuvelisa i-carbon diokside ngokukhawuleza njengomgubo omnye okanye amanqanaba, njengomgubo owenziweyo. Isoda yokubhaka ikwasetyenziswa njengomthombo wekharbon diokside ye-carbonlide kunye ne-buffer.in yongeza ekuhambeni, iSoda yokubhaka ineendlela ezininzi zekhaya. Isetyenziswe njenge-jikelele, i-Deodorizer, i-antmacid, i-anticress yomlilo, kunye neemveliso zobuqu ezifana nesiseko esibuthathaka kwi-8. I-thebicarbonate i-8. I-thebicarbonate ion (HCO3-) ine-ampPhotec Iipropathi, okuthetha ukuba isebenza njenge-acidor isiseko. Oku kunika isoda yokubhaka umthamo we-buff kunye nokukwazi ukubethelela iziseko zombini zecidds. I-odors yokutya eziphumela kwi-acidic okanye ezisisiseko ze-acidic zinokuchaphazeleka kunye ne-bakingssa kwi-odor-free ye-odor-free. Ngoba isodium Bicarbonate sisiseko esibuthathaka, sinendawo enkulu ye-acid acid.
Ukusetyenziswa kwesibini ngobukhulu kwi-sodium Bicarbonate, i-accounting malunga ne-25% yokuveliswa, injengesondlo sobuso sezolimo. Kwiinkomo kuyanceda ukugcina i-rumemen fiber fiber yokugaya; Ukuze inkukhu kuyanceda ukugcina ibhalansi ye-electrolyte ngokubonelela nge-sondiumsin yokutya, kunceda ubushushu obuqiqisayo, kwaye luphucula umgangatho weqanda.
I-sodium Bicarbonate isetyenziswa kwishishini lekhemikhali njengearhente ye-buff, i-blobrimogent, inkuthalo, kunye nekhephu lokondla. I-sodium Bicarbonate isetyenziswa kwi-sennindushulun ye-leatherting yokutshintsha kunye nokucoca i-Ph ngexesha lenkqubo ye-SODIM ifakwe kwi-antacid, i-abuff iarhente ye-ering, kunye nokwenziwa komthombo wekhabhoni I-Dioxide kwi-EFF Ervers. Uhlobo lwe-BCHemical BicChemical BicCheheSchemishers iqukethe i-sodium bicarbonate (okanye i-potasbonate) .Ukusetyenziswa kwe-bicarbonate kubandakanya i-bicarbonate ibandakanya i-pulp kunye ne-Wheding Foolling.

I-2. I-Sodium Bicarbonate yiarhente emnyama ene-PH ye-PH efanelekileyo 8.5 kwisisombululo se-1% nge-25 ° C. Isebenza nge-phosphates ye-phosphates yokutya (i-acidic yekhitshi) ukukhupha i-carbon dioksisi eyandiswa ngexesha lenkqubo yokuhambisa ukubonelela nge-volthi yonyuso kunye neempawu zokutya. Ikwasetyenziswa kwimigca eyomileyo yokudibanisa ukufumana i-boredlometion, ekhokelela apho amanzi adityaniswa kumxube oqulunqe i-sodium bicarbonate kunye ne-acid. Yinxalenye yomgubo wokubhaka. Ikwabizwa ngokuba yisoda ye-biking, i-bicarbonate yesoda, isoda i-sodium ye-carbonate, kunye ne-sodium hydrogen carbonate.

3. Ukwenziwa kweetyuwa ezininzi zesodium; umthombo we-CO2; isithako somgubo we-back, iityuwa ezikhulu neziselo; Kwizitshisi zomlilo, ukucoca izihlanganisi.

I-4. I-Sodium Bicarbonate (iSoda yokubhaka) yityuwa ye-inorganic esetyenziswa njengearhente ye-buffer kunye nolawulo lwe-PH, ikwasebenza njengomntu ongathathi cala. Isetyenziswe kwiindawo ezinolusu.
