Qhov sib txawv tseem ceeb ntawm borax thiab baking soda yog qhov borax yog sodium borate uas tshwm raws li cov khoom dawb whereas cov baking soda yog sodium bicarbonate uas tshwm li dawb crystals.
Borax yog ib lo lus uas piav qhia txog chav kawm ntawm cov tshuaj sib txuas uas suav nrog hydrated thiab anhydrous sodium borate. Tsis tas li ntawd, nws yog ib qho ntsev ntawm boric acid, uas yog ib qho khoom muaj nyob rau hauv ntau cov tshuaj detergents, tshuaj pleev ib ce thiab enamel glazes. Baking soda yog sodium bicarbonate, uas muaj ntau yam kev siv nrog rau kev ua noj, tshuaj tua kab, kev siv kho mob, ua cov tshuaj ntxuav, thiab lwm yam
Borax yog dab tsi?
Borax yog ib lub npe rau ob qho tib si tsis muaj dej los yog hydrated cov ntaub ntawv ntawm sodium borate. Nws yog ntsev ntawm boric acid. Cov tshuaj formula ntawm no compound yog Na2B4O7·10H 2O vim tias lub npe borax feem ntau yog siv rau daim ntawv decahydrate ntawm sodium borate. Nws zoo nkaus li cov khoom dawb. Cov molar mass ntawm no compound yog 381.38 g / mol. Cov tshuaj no yooj yim hloov mus rau hauv boric acid.
Na2B4O7·10H2 O + 2 HCl → 4 H3BO3 + 2 NaCl + 5 H2 O
Ntxiv mus, peb tuaj yeem siv qhov sib xyaw no (daim ntawv decahydrate) ua tus qauv tseem ceeb rau kev tshuaj xyuas titrimetric. Tias yog vim hais tias cov compound no txaus ruaj khov thiab ntshiab rau lub hom phiaj ntawd. Borax ib txwm tshwm sim hauv cov evaporite tso tawm los ntawm kev rov ua dua ntawm cov pas dej raws caij nyoog.
Daim duab 01: Tsob Ntoo Borax
Kev siv cov tshuaj no suav nrog cov hauv qab no;
- Raws li cov khoom xyaw hauv cov khoom ntxhua khaub ncaws thiab tshuaj ntxuav tes
- Ua buffers
- Tsim cov complexes nrog ntau yam tshuaj
- Rau qhov rho tawm ntawm cov kub hauv me me-kub mining
Baking Soda yog dab tsi?
Baking soda yog sodium bicarbonate. Nws yog ib qho inorganic khoom compound 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".

Kev siv loj ntawm cov khoom sib xyaw no yog raws li hauv qab no:
- Peb tuaj yeem siv qhov sib xyaw no rau kev ua noj ua zaub mov
- Yuav tshuaj tua kab tsuag
- Nws tuaj yeem nce alkalinity ntawm cov dej
- Siv tau raws li tshuaj tua kab mob me
- Siv tau rau nruab nrab ntawm cov kua qaub thiab cov hauv paus
Qhov txawv ntawm Borax thiab Baking Soda yog dab tsi?
Borax yog ib lub npe rau ob qho tib si anhydrous lossis hydrated daim ntawv ntawm sodium borate. Cov tshuaj formula ntawm borax yog Na2B4O7·10H2 O. Nws muaj cov molar loj 381.38 g / mol. Tsis tas li ntawd, nws yog ib qho tseem ceeb ua tus neeg saib xyuas, ua buffers, rau dej-softening, rau me me kub extractions, thiab lwm yam. Baking soda yog sodium bicarbonate. Cov tshuaj formula ntawm no compound yog NaHCO3 Nws molar mass yog 84 g / mol. Qhov tseem ceeb tshaj, nws muaj txiaj ntsig zoo li cov neeg sawv cev hauv kev ua noj, tshuaj tua kab, kom nce alkalinity, ua tshuaj tua kab mob me, thiab lwm yam. Cov no yog qhov sib txawv tseem ceeb ntawm borax thiab baking soda.
Summary – Borax vs Baking Soda
Ob qho tib si borax thiab baking soda yog cov npe ntawm ob hom tshuaj sib txawv. Qhov sib txawv ntawm borax thiab ci dej qab zib yog tias borax yog ib qho sodium borate uas zoo nkaus li cov khoom dawb whereas lub ci dej qab zib yog sodium bicarbonate uas tshwm li dawb crystals.
