Mtengo Wabwino Wopanga Sodium Bicarbonate CAS: 144-55-8

1. Sodium bicarbonate, yomwe imagwiritsidwa ntchito ngati baking soda ndi baking powder, ndiyo chinthu chodziwika kwambiri chopangira chofufumitsa. Baking soda ikawonjezedwa ku chosakaniza, imachita ndi asidi kuti ipange carbon dioxide. Yankho lake likhoza kuimiridwa motere: NaHCO3(s) + H+ → Na+(aq) + H2O(l) +CO2(g), pomwe H+ imaperekedwa ndi asidi. Baking powders imakhala ndi baking soda ngati chinthu chachikulu pamodzi ndi asidi ndi zosakaniza zina. Kutengera ndi kapangidwe kake, baking powders imatha kupanga carbon dioxide mwachangu ngati ufa wochita kamodzi kapena pang'onopang'ono, monga momwe zimakhalira ndi ufa wochita kawiri. Baking soda imagwiritsidwanso ntchito ngati gwero la carbon dioxide pa carbonated devices komanso ngati buffer. Kupatula baking soda, baking soda imagwiritsidwa ntchito m'nyumba zambiri. Amagwiritsidwa ntchito ngati chotsukira wamba, deodorizer, antacid, choletsa moto, komanso mu zinthu zaumwini monga mankhwala otsukira mano. Sodium bicarbonate ndi maziko ofooka mu yankho lamadzi, okhala ndi pH pafupifupi 8. Thebicarbonate ion (HCO3-) ili ndi mphamvu ya amphoteric, zomwe zikutanthauza kuti imatha kugwira ntchito ngati acid kapena maziko. Izi zimapatsa baking soda mphamvu yopumira komanso kuthekera kothetsa asidi ndi maziko onse. Fungo la chakudya lochokera ku acid kapena mankhwala oyambira limatha kusinthidwa ndi baking soda kukhala mchere wopanda fungo. Chifukwa sodium bicarbonate ndi maziko ofooka, ili ndi kuthekera kwakukulu kothetsa fungo la asidi.
Kugwiritsa ntchito kwachiwiri kwakukulu kwa sodium bicarbonate, komwe kumapanga pafupifupi 25% ya kuchuluka kwa chakudya chonse, ndi chakudya chowonjezera chaulimi. Mu ng'ombe zimathandiza kusunga pH ya m'mimba ndikuthandizira kugaya ulusi; pa nkhuku zimathandiza kusunga electrolyte bwino mwa kupereka sodium muzakudya, zimathandiza nkhuku kupirira kutentha, komanso zimawonjezera ubwino wa chipolopolo cha dzira.
Sodium bicarbonate imagwiritsidwa ntchito mumakampani opanga mankhwala ngati chothandizira kupukutira, chopukutira, chothandizira, komanso chothandizira mankhwala. Sodium bicarbonate imagwiritsidwa ntchito mumakampani opanga utoto wa zikopa pochiza ndi kuyeretsa zikopa komanso kuwongolera pH panthawi yopukutira. Kutenthetsa sodium bicarbonate kumapanga sodium carbonate, yomwe imagwiritsidwa ntchito popanga sopo ndi magalasi. Sodium bicarbonate imaphatikizidwa mu mankhwala kuti ikhale ngati chothandizira kupha asidi, kupukutira, komanso mu mapangidwe ngati gwero la carbon dioxide m'mapiritsi otulutsa mpweya. Zozimitsira moto zamtundu wa BC zouma zimakhala ndi sodium bicarbonate (kapena potassium bicarbonate). Ntchito zina za bicarbonate zimaphatikizapo kukonza zamkati ndi mapepala, kukonza madzi, ndi kuboola zitsime zamafuta.

2. Sodium Bicarbonate ndi chinthu choyambitsa chofufumitsa chokhala ndi pH ya pafupifupi 8.5 mu yankho la 1% pa 25°C. Imagwira ntchito ndi ma phosphates a mtundu wa chakudya (mankhwala oyambitsa chofufumitsa cha acidic) kuti itulutse carbon dioxide yomwe imakula panthawi yophika kuti ipatse chophikidwacho kuchuluka kwakukulu komanso kukoma kokoma. Imagwiritsidwanso ntchito mu zakumwa zouma kuti ipange carbonation, zomwe zimachitika madzi akawonjezeredwa ku chophwanyidwa chokhala ndi sodium bicarbonate ndi asidi. Ndi gawo la ufa wophikira. Imatchedwanso baking soda, bicarbonate of soda, sodium acid carbonate, ndi sodium hydrogen carbonate.

3. Kupanga mchere wambiri wa sodium; gwero la CO2; chosakaniza cha ufa wophikira, mchere wotentha ndi zakumwa; mu zozimitsira moto, zotsukira zinthu.

4. Sodium bicarbonate (baking soda) ndi mchere wosapangidwa womwe umagwiritsidwa ntchito ngati chosungira komanso chosinthira pH, umagwiranso ntchito ngati choletsa kukalamba kwa khungu. Umagwiritsidwa ntchito mu ufa wosalala khungu.
