Tuam Tshoj Tus Nqi Zoo Sodium Bicarbonate CAS: 144-55-8

1. Sodium bicarbonate, siv nyob rau hauv daim ntawv ntawm baking soda thiab ci hmoov, yog cov feem ntau leavening neeg sawv cev.Thaum ci dej qab zib, uas yog ib qho khoom alkaline, ntxiv rau kev sib tov, nws reacts nrog cov khoom xyaw acid los tsim cov pa roj carbon dioxide.Cov tshuaj tiv thaiv tuaj yeem sawv cev raws li: NaHCO3(s) + H + → Na + (aq) + H2O(l) + CO2(g), qhov H + yog muab los ntawm cov kua qaub.Baking hmoov muaj baking soda ua cov khoom tseem ceeb nrog rau cov kua qaub thiab lwm yam khoom xyaw.Raws li kev tsim, bakingpowders tuaj yeem tsim cov pa roj carbon dioxide sai sai raws li cov hmoov ua haujlwm ib zaug lossis hauv theem, xws li cov hmoov ua ob zaug.Baking soda kuj yog siv los ua cov pa roj carbon dioxide rau carbonated dej qab zib thiab ua tsis tau.Ntxiv rau ci, ci dej qab zib muaj ntau tsev neeg siv.Nws yog siv los ua cov tshuaj ntxuav tes, tshuaj tua kab mob, tshuaj tua kab mob, tshuaj tua hluav taws, thiab hauv cov khoom siv ntawm tus kheej xws li tshuaj txhuam hniav.Sodium bicarbonate yog lub hauv paus tsis muaj zog hauv cov tshuaj aqueous, nrog rau pH txog li 8. Thebicarbonate ion (HCO3-) muaj amphoteric. cov khoom, uas txhais tau tias nws tuaj yeem ua raws li ib qho acidor hauv paus.Qhov no muab baking soda muaj peev xwm buff ering thiab muaj peev xwm ua kom tsis zoo ntawm ob qho tib si acids thiab bases.Cov ntxhiab tsw ntawm cov khoom noj uas tshwm sim los ntawm cov kua qaub lossis cov ntsiab lus yooj yim tuaj yeem ua rau nruab nrab nrog bakingsoda rau hauv cov ntsev tsis muaj ntxhiab tsw.Vim tias sodium bicarbonate yog lub hauv paus tsis muaj zog, nws muaj peev xwm ua kom tsis muaj kua qaub.
Qhov thib ob loj tshaj plaws ntawm kev siv sodium bicarbonate, suav txog kwv yees li 25% ntawm tag nrho cov khoom tsim tawm, yog raws li kev ua liaj ua teb pub ntxiv.Hauv nyuj nws pab tswj rumen pH andaids fiber ntau digestibility;rau cov nqaij qaib nws pab tswj cov electrolyte tshuav nyiaj li cas los ntawm kev muab sodium nyob rau hauv cov zaub mov, pab fowl tiv tshav kub, thiab txhim kho qe zoo.
Sodium bicarbonate yog siv nyob rau hauv kev lag luam tshuaj raws li ib tug buff ering tus neeg sawv cev, ib tug blowingagent, ib tug catalyst, thiab ib tug chemical feedstock.Sodium bicarbonate yog siv nyob rau hauv tawv tanningindustry rau pretreating thiab tu hides thiab tswj pH thaum lub sij hawm tanning txheej txheem. Cua sov sodium bicarbonate ua sodium carbonate, uas yog siv rau xab npum thiab iav. ering tus neeg sawv cev, thiab nyob rau hauv formulations raws li ib qhov chaw ntawm carbon dioxide nyob rau hauv eff ervescent ntsiav tshuaj.Drychemical type BC fire extinguishers muaj sodium bicarbonate (los yog potassium bicarbonate).Lwm yam kev siv bicarbonate muaj xws li cov ntaub so ntswg thiab cov ntawv ua, kev kho dej, thiab roj qhov dej.

2. Sodium Bicarbonate yog ib qho tshuaj tua kab mob nrog ph ntawm kwv yees li 8.5 hauv 1% tshuaj ntawm 25 ° c.Nws ua haujlwm nrog cov zaub mov qib phosphates (acidic leavening compounds) kom tso cov pa roj carbon dioxide uas nthuav dav thaum lub sij hawm ci los muab cov ci ci nrog qhov ntim thiab kev sib tw noj zoo.Nws kuj tseem siv rau hauv cov dej sib tov qhuav kom tau txais carbonation, uas tshwm sim thaum dej ntxiv rau qhov sib xyaw uas muaj cov sodium bicarbonate thiab cov kua qaub.nws yog ib feem ntawm ci hmoov.Nws tseem hu ua ci dej qab zib, bicarbonate ntawm dej qab zib, sodium acid carbonate, thiab sodium hydrogen carbonate.

3. Kev tsim khoom ntawm ntau cov ntsev ntsev;qhov chaw ntawm CO2;cov khoom xyaw ntawm ci hmoov, effervescent ntsev thiab dej haus;nyob rau hauv cov hluav taws tua hluav taws, ntxuav Compounds.

4. Sodium bicarbonate (baking soda) yog ib qho ntsev inorganic siv los ua tus neeg sawv cev buffering thiab pH adjuster, nws kuj ua haujlwm tsis zoo.Nws yog siv nyob rau hauv daim tawv nqaij-smooth hmoov.
