Qhov sib txawv tseem ceeb ntawm calcium carbonate thiab calcium bicarbonate yog tias calcium carbonate molecule muaj Ca, C, thiab O tshuaj ntsiab lus thaum calcium bicarbonate muaj Ca, C, O, thiab H chemical.

Calcium carbonate yog cov carbonate ntawm calcium uas muaj cov tshuaj formula CaCO ₃ Nws tshwm sim ib txwm muaj thiab zoo li cov khoom dawb. Ntawm qhov tsis sib xws, Calcium bicarbonate tsis yog ib qho khoom, nws tshwm sim raws li cov tshuaj aqueous nkaus xwb. Cov tshuaj formula ntawm no compound yog Ca(HCO₃)₂

Calcium Carbonate yog dab tsi?

Calcium carbonate yog cov carbonate ntawm calcium uas muaj cov tshuaj formula CaCO_{3Cov tshuaj no 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). Cov tshuaj no tshwm sim li dawb hexagonal crystals lossis hmoov, thiab nws tsis muaj ntxhiab.}

Ntxiv mus, nws 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 dawb huv siv qhov chaw quarried ntshiab xws li marble. Thaum calcium carbonate reacts nrog acids, nws tsim CO₂ roj. Thaum nws tshwm sim nrog dej, nws tsim calcium hydroxide. Tsis tas li ntawd, nws tuaj yeem raug thermal decomposition tso CO_{2 roj.}

Calcium Bicarbonate yog dab tsi?

Calcium bicarbonate yog carbonate ntawm calcium uas muaj cov tshuaj formula Ca(HCO₃)2 _{Nws tsis tshwm sim raws li cov khoom, tsuas yog muaj raws li ib tug aqueous tov. Cov tshuaj no muaj calcium ions (Ca}2+^{), bicarbonate ions (HCO}3_–) thiab CO ³₂- nrog rau cov pa roj carbon dioxide yaj. Txawm li cas los xij, qhov ntau ntawm cov ions no nyob ntawm pH ntawm qhov nruab nrab, uas txhais tau hais tias, cov ions sib txawv predominate ntawm cov pH sib txawv.

Cov molar loj ntawm cov tshuaj no yog 162.11 g / mol. Cov ntaub ntawv no tshwm sim thaum cov dej nag uas muaj cov pa roj carbon dioxide ua rau cov limestone. Yog li ntawd, qhov sib xyaw no ntxuav nrog dej nag.

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

Calcium carbonate yog cov carbonate ntawm calcium uas muaj cov tshuaj formula CaCO ₃ Cov molar pawg ntawm cov tshuaj no yog 100 g / mol. Tsis tas li ntawd, cov molecules no muaj Ca, C, thiab O tshuaj lom neeg. Calcium bicarbonate yog carbonate ntawm calcium uas muaj cov tshuaj formula Ca(HCO₃)_{2 Cov molar pawg ntawm cov tshuaj no yog 162.11 g / mol. Tsis tas li ntawd, cov molecules no muaj Ca, C, O thiab H chemical.}

Summary – Calcium Carbonate vs Calcium Bicarbonate

Cov carbonate loj ntawm calcium yog calcium carbonate thiab calcium bicarbonate. Qhov sib txawv tseem ceeb ntawm calcium carbonate thiab calcium bicarbonate yog cov calcium carbonate molecule muaj Ca, C thiab O tshuaj ntsiab lus thaum calcium bicarbonate muaj Ca, C, O, thiab H tshuaj ntsiab lus.
