Qhov sib txawv tseem ceeb ntawm calcium acetate thiab calcium carbonate yog calcium carbonate muaj cov calcium uas muaj ntau dua li calcium acetate.

Calcium acetate yog cov tshuaj lom neeg uas tuaj yeem txheeb xyuas tau tias yog calcium ntsev ntawm acetic acid. Calcium carbonate yog carbonate ntawm calcium thiab muaj cov tshuaj formula CaCO3. Ob leeg yog calcium ntsev tebchaw uas muaj ionic natures.

Calcium Acetate yog dab tsi?

Calcium acetate yog cov tshuaj lom neeg uas tuaj yeem txheeb xyuas tau tias yog calcium ntsev ntawm acetic acid. Cov tshuaj no muaj cov tshuaj formula Ca(C2H3O2)2. Txawm hais tias tus qauv lub npe ntawm cov tshuaj no yog calcium acetate, nws lub npe hu ua calcium ethanoate. Nws tseem hu ua acetate ntawm txiv qaub.

Daim duab 01: Cov qauv tshuaj ntawm Calcium Acetate

Kev tsim cov calcium acetate tuaj yeem ua tiav los ntawm kev ntub dej calcium carbonate lossis hydrated txiv qaub hauv vinegar. Qhov chaw ntawm calcium carbonate muaj xws li qe, limestone, marble, thiab lwm yam carbonate pob zeb.

Muaj ntau yam kev siv calcium acetate, suav nrog txo qis cov ntshav phosphate, ua cov khoom noj ntxiv, ua kom ruaj khov rau cov khoom noj, tsim cov taum pauv, ua cov khoom pib rau acetone ntau lawm, thiab lwm yam.

Cov molar loj ntawm calcium acetate yog 158.16 g / mol. Nws zoo nkaus li cov khoom dawb uas yog hygroscopic. Ntxiv mus, cov khoom no yog me ntsis tsw nrog ib tug acetic acid tsw. Qhov ceev ntawm calcium acetate yog li 1.5 g / cm3. Thaum nws melting point los yog kub dua, peb tuaj yeem soj ntsuam qhov decomposition ntawm calcium acetate rau hauv calcium carbonate thiab acetone. Tsis tas li ntawd, calcium acetate yog me ntsis soluble hauv methanol, thiab hydrazine thaum nws tsis soluble hauv acetone, ethanol, thiab benzene.

Calcium Carbonate yog dab tsi?

Calcium carbonate yog carbonate ntawm calcium uas muaj cov tshuaj formula CaCO3. Calcium carbonate ib txwm tshwm sim li limestone, chalk, calcite, thiab lwm yam. Yog li ntawd, nws yog ib qho khoom siv hauv pob zeb. Piv txwv li: calcite lossis aragonite (Limestone muaj ob daim ntawv no). Calcium carbonate tshwm sim li dawb hexagonal crystals lossis hmoov, thiab nws tsis muaj ntxhiab.

Daim duab 02: Calcium Carbonate Solid Form

Ntxiv mus, calcium carbonate muaj ib qho chalky saj. Cov molar loj ntawm cov tshuaj no yog 100 g / mol, thiab lub melting point yog 1,339 ° C (rau daim ntawv calcite). Txawm li cas los xij, nws tsis muaj qhov kub hnyiab vim tias qhov sib xyaw no decomposes ntawm qhov kub thiab txias. Peb tuaj yeem tau txais qhov sib xyaw no los ntawm kev khawb cov calcium uas muaj cov zaub mov. Tab sis daim ntawv no tsis yog dawb huv. Peb tuaj yeem tau txais daim ntawv ntshiab uas siv cov khoom siv dawb huv xws li marble. Thaum calcium carbonate reacts nrog acids, nws tsim CO2 roj. Thaum nws tshwm sim nrog dej, nws tsim calcium hydroxide. Ntxiv nrog rau cov no, nws tuaj yeem ua rau thermal decomposition, tso CO2 roj.

Qhov txawv ntawm Calcium Acetate thiab Calcium Carbonate yog dab tsi?

Calcium acetate yog cov tshuaj lom neeg uas tuaj yeem txheeb xyuas tau tias yog calcium ntsev ntawm acetic acid. Calcium carbonate yog carbonate ntawm calcium uas muaj cov tshuaj formula CaCO3. Qhov sib txawv tseem ceeb ntawm calcium acetate thiab calcium carbonate yog tias calcium acetate muaj qis dua ntawm calcium elemental, thaum calcium carbonate muaj cov calcium uas muaj calcium ntau.

Cov hauv qab no qhia txog qhov sib txawv ntawm calcium acetate thiab calcium carbonate hauv daim ntawv tabular rau ib sab kev sib piv.

Summary – Calcium Acetate vs Calcium Carbonate

Ob qho calcium acetate thiab calcium carbonate yog ionic compounds. Qhov sib txawv tseem ceeb ntawm calcium acetate thiab calcium carbonate yog lawv cov ntsiab lus calcium. Calcium carbonate muaj cov ntsiab lus calcium ntau dua li calcium acetate
