Umenzi Ixabiso Elihle I-Sodium Bicarbonate CAS: 144-55-8

1. I-sodium bicarbonate, esetyenziswa ngendlela ye-baking soda kunye ne-baking powder, yeyona nto ixhaphakileyo yokugalela igwele. Xa i-baking soda, eyinto ye-alkaline, yongezwa kumxube, iphendula kunye nesithako se-asidi ukuvelisa i-carbon dioxide. Impendulo ingamelwa ngolu hlobo: NaHCO3(s) + H+ → Na+(aq) + H2O(l) +CO2(g), apho i-H+ ibonelelwa yi-asidi. Ii-baking powders ziqulathe i-baking soda njengesithako esiphambili kunye ne-asidi kunye nezinye izithako. Ngokuxhomekeke kwifomyula, ii-baking powders zinokuvelisa i-carbon dioxide ngokukhawuleza njenge-single action powder okanye ngamanqanaba, njengakwi-double-action powder. I-baking soda ikwasetyenziswa njengomthombo we-carbon dioxide kwii-carbonated beverages kunye ne-buffer. Ukongeza kwi-baking, i-baking soda inezinto ezininzi ezisetyenziswa ekhaya. Isetyenziswa njengesicoci esiqhelekileyo, i-deodorizer, i-antacid, i-stop depressant, nakwimveliso zobuqu ezifana ne-toothpaste. I-sodium bicarbonate sisiseko esibuthathaka kwisisombululo samanzi, esine-pH emalunga ne-8. I-ion ye-bicarbonate (HCO3-) ineempawu ze-amphoteric, oko kuthetha ukuba inokusebenza njenge-asidi okanye isiseko. Oku kunika i-baking soda amandla okucoca kunye nokukwazi ukuphelisa zombini i-asidi kunye neziseko. Ivumba lokutya elivela kwi-acidic okanye kwi-basic compounds linokususwa nge-baking soda libe ziityuwa ezingenavumba. Ngenxa yokuba i-sodium bicarbonate sisiseko esibuthathaka, inamandla amakhulu okuphelisa ivumba le-asidi.
Ukusetyenziswa kwesibini ngobukhulu kwe-sodium bicarbonate, emalunga ne-25% yemveliso iyonke, kukutya kwezolimo. Kwiinkomo inceda ukugcina i-rumen pH kwaye inceda ukugaywa kwefayibha; kwiinkukhu inceda ukugcina ibhalansi ye-electrolyte ngokubonelela nge-sodium ekutyeni, inceda iintaka ukuba zinyamezele ubushushu, kwaye iphucula umgangatho weqokobhe leqanda.
I-sodium bicarbonate isetyenziswa kwishishini leekhemikhali njenge-arhente yokucoca, i-blowagent, i-catalyst, kunye ne-feedstock yeekhemikhali. I-sodium bicarbonate isetyenziswa kwishishini le-tanning yesikhumba ekunyangeni nasekucoceni izikhumba kunye nokulawula i-pH ngexesha lenkqubo yokushushumbisa. I-sodium bicarbonate efudumezayo ivelisa i-sodium carbonate, esetyenziselwa isepha kunye nokwenza iglasi. I-sodium bicarbonate ifakwa kwiyeza ukuze isebenze njenge-antacid, i-abuff ering agent, nakwimixube njengomthombo we-carbon dioxide kwiipilisi ze-efrescent. Izitshizi zomlilo ze-BC ezomileyo ziqulethe i-sodium bicarbonate (okanye i-potassium bicarbonate). Ezinye iindlela zokusebenzisa i-bicarbonate ziquka ukucubungula i-pulp kunye nephepha, unyango lwamanzi, kunye nokugrumba i-oyile.

2. I-Sodium Bicarbonate sisithako esikhupha igwele esine-ph emalunga ne-8.5 kwisisombululo se-1% kwi-25°C. Isebenza nee-phosphates ze-food grade (ii-compounds zegwele ezine-acidic) ukukhupha i-carbon dioxide eyanda ngexesha lenkqubo yokubhaka ukuze inike ukutya okubhakiweyo umthamo owandisiweyo kunye neempawu zokutya ezithambileyo. Ikwasetyenziswa kwiziselo ezixutywe nomxube owomileyo ukuze ifumane i-carbonation, ephumela xa amanzi efakwa kumxube oqulethe i-sodium bicarbonate kunye ne-asidi. yinxalenye ye-baking powder. Ikwabizwa ngokuba yi-baking soda, i-bicarbonate yesoda, i-sodium acid carbonate, kunye ne-sodium hydrogen carbonate.

3. Ukwenziwa kweetyuwa ezininzi zesodium; umthombo weCO2; isithako se-baking powder, iityuwa ezitshisayo kunye neziselo; kwizicimi-mlilo, iiCompounds zokucoca.

4. I-Sodium bicarbonate (i-baking soda) yityuwa engaphiliyo esetyenziswa njenge-buffering agent kunye ne-pH adjuster, ikwasebenza njenge-neutralizer. Isetyenziswa kwimibhobho egudisayo ulusu.
