Fungsi sodium bicarbonate

Kev qhia tshwj xeeb

Sodium bicarbonate yog muab rho tawm siv kev daws teeb meem los ntawm kev txhaj tshuaj kub los ntawm kev txhaj tshuaj kub kom yaj qhov twg nws tshwm sim 2, {ko taw hauv qab saum npoo. Qhov yaj tau hais tias nws tau nqus rau saum npoo uas nws tau kho kom rov zoo li nhaco₃los ntawm kev daws teeb meem. Nws tseem tuaj yeem tsim los ntawm cov nyiaj hauv TRAAs, uas yog qhov chaw sodium carbon monoxide (saib sodium carbonate).

Daim ntawv thov

Sodium bicarbonate, siv nyob rau hauv lub formof ci dej qab zib thiab ci hmoov, yog qhov feem ntau cov neeg sawv cev hauv keeb kwm. Thaum ci dej qab zib, uas yog ib qho khoom noj khoom haus alkaline, ntxiv rau kev sib xyaw, nws cuam tshuam nrog cov tshuaj muaj kua qaub ua kom tsim khoom. Cov tshuaj tiv thaiv tuaj yeem raug sawv cev raws li: Nahco3 (s) h + → naj npawb rau + (l) + h + yog muab los ntawm cov kua qaub. Ci txau muaj cov dej qab zib muaj cov dej qab zib ua ib qho tseem ceeb nrog cov acid thiab lwm yam khoom xyaw. Ua raws li cov qauv tsim, ci ci tuaj yeem tsim cov pa roj carbon dioxide sai sai sai li ib qho kev nqis tes ua lossis hauv theem, raws li cov hmoov adouble-nqis. Ci Dej qab zib kuj tau siv los ua lub hauv paus rau cov pa roj carbon dioxide rau cov carbon cais rau baking, ci dej qab zib muaj ntau tsev neeg siv. Nws yog siv los ua tus deodStanser, ib qho kev tawm tsam, ib qho hluav taws kub ua rau muaj cov tshuaj txhuam hniav uas muaj zog, thiab hauv cov tshuaj txhuam hniav uas muaj zog, thiab cov khoom siv tau zoo li nws muaj peev xwm ua raws li ib qho kua qaub. Qhov no muab Baking dej qab zib ib buff ering muaj peev xwm thiab muaj peev xwm los nruab nrab ob qho tib si acidsland hauv paus. Cov zaub mov tsw tshwm los ntawm acidic lossis cov kab sib txuas yooj yim tuaj yeem cuam tshuam nrog ci ci rau cov ntsev tsis muaj ntxhiab. Vim tias nws yog lub hauv paus tsis muaj zog, nws muaj lub peev xwm ntau dua neutalize acid opors.

Cov Qauv Ntau Lawm

Feem ntau sodium Bicarbonate hauv Tebchaws Meskas yog ua synthetically los ntawm cov tshuaj tiv thaiv ntawm sodium carbonate nrog cov pa roj carbon dioxide: na₂Co las_{3 (AQ)} + H₂O_(l)+ CO_2(g)2na_{3 (AQ)}Cov. Nws kuj tseem tsim tau siv cov txheej txheem daws teeb meem, uas siv ammonia, carbon dioxide, thiab ntsev kom tsim nws raws li cov lus hais hauv qab no: 2NH_3(g)+ CO_2(g) + H₂O_(l)→ (nh₄)₂Co las_{3 (AQ)}

Ua tsaug rau koj cov kev mus ntsib thiab tos txais koj cov lus nug zoo!
