Qhov sib txawv tseem ceeb ntawm Potassium Carbonate thiab Potassium Bicarbonate yog tias potassium carbonate molecule tsis muaj hydrogen atoms nyob rau hauv nws cov qauv tshuaj whereas poov tshuaj bicarbonate molecule muaj ib hydrogen atom nyob rau hauv nws cov qauv tshuaj.
Ob leeg no yog cov ntsev ntsev; Yog li, yog cov tshuaj alkaline heev.
YPotassium Carbonate yog dab tsi?
Potassium carbonate yog cov ntsev ntsev uas muaj cov tshuaj formula K2CO3. Nws yog dej soluble heev thiab tsim ib qho kev daws teeb meem alkaline aqueous. Tsis tas li ntawd, nws yog heev deliquescent. Yog li ntawd, nws absorbs dej vapor los ntawm qhov chaw thiab dissolves.
Daim duab 01: Potassium Carbonate
Khoom ntawm Potassium Carbonate
Qee cov lus tseeb txog potassium carbonate yog raws li hauv qab no:
- Chemical formula=K2CO3
- Molar mass=138.2 g/mol
- melting point=891 °C
- Boiling point=decomposes
- Zoo=dawb tawv
- dej solubility=dej soluble heev
Potassium carbonate ntau lawm suav nrog electrolysis ntawm potassium chloride (KCl). Qhov no muab cov poov tshuaj hydroxide (KOH). Tom qab ntawd carbonation ntawm qhov no siv cov pa roj carbon dioxide tsim cov poov tshuaj carbonate.
Potassium Bicarbonate yog dab tsi?
Potassium bicarbonate yog cov ntsev ntsev uas muaj cov tshuaj tshuaj KHCO3. Nws yog xim tsis muaj xim thiab tsw ntxhiab thiab nws zoo li cov muaju dawb. Qhov no compound yog me ntsis yooj yim. Tsis tas li ntawd, nws tsis tshua muaj tshwm sim nyob rau hauv daim ntawv ntawm cov ntxhia pob zeb; kalicinite.
Daim duab 02: Potassium Bicarbonate
Khoom ntawm Potassium Bicarbonate
Qee cov lus tseeb txog poov tshuaj bicarbonate yog raws li hauv qab no:
- Chemical formula=KHCO3
- Molar mass=100.12 g/mol
- Meting point=292 °C
- Boiling point=decomposes
- Zoo=dawb crystals
- dej solubility=dej soluble
Ib qho kev siv loj ntawm cov khoom sib xyaw no yog cov tshuaj tua kab mob rau cov khoom bakery. Tsis tas li ntawd, nws yog ib qho tseem ceeb ntxiv hauv winemaking los tswj pH. Ntxiv mus, poov tshuaj bicarbonate yog ib tug muaj zog tua hluav taws tua neeg sawv cev thiab ib tug zoo fungicide.
Qhov txawv ntawm Potassium Carbonate thiab Potassium Bicarbonate yog dab tsi?

Summary – Potassium Carbonate vs Potassium Bicarbonate
Potassium carbonate thiab bicarbonate yog cov ntsev ntsev uas yog cov ntsiab lus yooj yim. Qhov sib txawv ntawm cov poov tshuaj carbonate thiab potassium bicarbonate yog tias poov tshuaj carbonate molecule tsis muaj hydrogen atoms nyob rau hauv nws cov qauv tshuaj hos poov tshuaj bicarbonate molecule muaj ib hydrogen atom nyob rau hauv nws cov qauv tshuaj.
