Qhov sib txawv tseem ceeb ntawm cov dej qab zib thiab cov dej qab zib yog cov dej qab zib muaj sodium carbonate, thaum ci dej qab zib muaj sodium bicarbonate.
Soda crystals thiab baking soda yog carbonate cov ntaub ntawv ntawm sodium uas muaj cov tshuaj sib txawv thiab cov kev siv sib txawv. Soda crystals kuj feem ntau hu ua soda soda lossis soda tshauv. Soda crystals muaj txiaj ntsig zoo li dej softener hauv kev ntxhua khaub ncaws vim lawv tuaj yeem sib tw nrog magnesium thiab calcium ions. Ntawm qhov tod tes, ci dej qab zib yog qhov tseem ceeb hauv kev ua noj ua haus raws li cov tshuaj tua kab, raws li kev tswj xyuas kab tsuag kom tua kab laum, ua cov tshuaj uas tuaj yeem tsim cov alkalinity ntawm cov dej, ua cov tshuaj tua kab mob me me, thiab ua cov tshuaj tua kab mob rau cov kua qaub. thiab bases.
Soda Crystals yog dab tsi?
Soda crystals tseem hu ua soda soda lossis soda tshauv. Cov tshuaj no muaj cov tshuaj formula Na2CO3. Nws lub npe tshuaj yog sodium carbonate. Feem ntau daim ntawv ntawm no compound muaj nyob rau hauv daim ntawv ntawm crystalline decahydrate. Soda crystals tau yooj yim effloresce los ua cov hmoov dawb. Cov hmoov dawb no yog daim ntawv monohydrate ntawm cov tshuaj no. Daim ntawv ntshiab ntawm sodium carbonate yog hygroscopic.

Cov npe ntxuav dej qab zib lossis dej qab zib tshauv tuaj nrog nws siv hauv tsev. Nws muaj txiaj ntsig zoo li cov tshuaj ntxuav dej hauv kev ntxhua khaub ncaws vim nws tuaj yeem sib tw nrog magnesium thiab calcium ions (uas ua rau cov dej tawv) kom tsis txhob muaj kev sib txuas ntawm cov ions thiab cov tshuaj ntxuav tes uas peb siv. Txawm li cas los xij, kev ntxuav dej qab zib tsis tuaj yeem tiv thaiv kev scaling. Ntxiv mus, peb tuaj yeem siv qhov sib xyaw no los tshem tawm cov av xws li roj, stain, roj, thiab lwm yam.
Peb tuaj yeem yuav cov xab npum ntxhua khaub ncaws los ntawm cov khw muag khoom yooj yim. Txawm li cas los xij, peb tuaj yeem ua nws hauv tsev thiab. Peb tsuas tuaj yeem ci ci dej qab zib (rau ib nrab teev ntawm 400 Fahrenheit) los hloov nws mus rau hauv dej qab zib. Qhov kev hloov dua siab tshiab no ua tau vim tias tsuas muaj qhov sib txawv me ntsis ntawm baking soda thiab soda soda; baking soda yog sodium bicarbonate, yog li yog tias peb ua kom sov cov tshuaj no, nws yuav ua rau sodium carbonate, dej vapour, thiab carbon dioxide.
Baking Soda yog dab tsi?
Baking soda yog cov tshuaj lom neeg sodium bicarbonate. Nws yog ib qho inorganic khoom uas tshwm li dawb crystals. Nws muaj cov tshuaj formula NaHCO3, thiab molar mass yog 84 g / mol. Ntxiv mus, nws yog ntsev uas muaj sodium cations thiab bicarbonate anions. Daim ntawv tshwm sim ntawm qhov sib xyaw no yog "nahcolite".

Cov ntawv thov ci dej qab zib suav nrog lub hom phiaj ua noj ua cov tshuaj tua kab, ua cov tshuaj tua kab tua kab, ua cov tshuaj uas tuaj yeem nce cov alkalinity ntawm cov dej, ua cov tshuaj tua kab mob me me, thiab ua cov tshuaj tua kab mob. acids thiab bases.
Dab tsi zoo sib xws ntawm Soda crystals thiab Baking Soda?
- Soda crystals thiab baking soda yog carbonates ntawm sodium ion.
- Ob lub tebchaw muaj sodium, carbon, thiab oxygen atoms.
- Lawv yog alkaline compounds.
- Cov tshuaj no tuaj yeem siv rau hauv pas dej da dej los kho cov alkalinity ntawm cov dej hauv pas dej.
Qhov txawv ntawm Soda Crystals thiab Baking Soda yog dab tsi?
Soda crystals thiab baking soda yog cov tshuaj tseem ceeb hauv peb lub neej txhua hnub. Lawv yog ob qho tib si tshuaj lom neeg sib txuas. Baking soda yog cov tshuaj siv tshuaj sodium bicarbonate. Qhov sib txawv tseem ceeb ntawm cov dej qab zib thiab cov baking soda yog cov dej qab zib muaj cov sodium carbonate, thaum ci dej qab zib muaj sodium bicarbonate ua cov tshuaj lom neeg. Tsuas muaj qhov sib txawv me ntsis ntawm cov dej qab zib muaju thiab ci dej qab zib; Yog hais tias peb sov sodium bicarbonate, nws yields sodium carbonate, dej vapour, thiab carbon dioxide.
Cov ntawv qhia hauv qab no qhia qhov sib txawv ntawm cov dej qab zib muaju thiab ci dej qab zib hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Soda Crystals vs Baking Soda
Soda crystals yog ntxuav dej qab zib los yog dej qab zib tshauv. Baking soda yog ib yam khoom muaj nyob rau hauv lub ncuav mog qab zib thiab lwm yam khoom bakery ib yam nkaus. Soda crystals yog cov tshuaj sib xyaw uas muaj cov tshuaj formula Na2CO3 thaum ci dej qab zib muaj cov tshuaj formula Na2CO3. Qhov sib txawv tseem ceeb ntawm cov dej qab zib thiab cov baking soda yog cov dej qab zib muaj sodium carbonate, thaum ci dej qab zib muaj sodium bicarbonate.
