Qhov sib txawv tseem ceeb ntawm calcium chloride thiab calcium chloride dihydrate yog calcium chloride yog anhydrous thaum calcium chloride dihydrate yog ib daim ntawv hydrated calcium chloride.
Calcium chloride yog ib qho inorganic compound. Nws feem ntau tshwm sim raws li hydrated compound. Qhov no txhais tau tias calcium chloride molecules muaj nyob rau hauv kev koom tes nrog dej molecules. Feem ntau cov hydrate yog dihydrate.
Calcium Chloride yog dab tsi?
Calcium chloride yog ib qho inorganic compound uas muaj CaCl 2 Nws yog chloride ntsev ntawm calcium hlau. Tsis tas li ntawd, qhov sib xyaw no tshwm sim ua dawb crystalline khoom ntawm chav tsev kub. Nws yog dej-soluble heev. Tsis tas li ntawd, nws yog hygroscopic heev. Yog li ntawd, peb tuaj yeem siv nws ua tus desiccant. Calcium chloride feem ntau muaj nyob rau hauv daim ntawv hydrated. i.e. CaCl2(H2O)x, where x=0, 1, 2, 4, thiab 6. Nyob rau hauv nws daim ntawv anhydrous, lub melting point ntawm 772-775 °C.
Calcium chloride muaj cov hauv qab no siv:
- Raws tus neeg sawv cev los tiv thaiv kev tsim dej khov
- Kom txo hmoov av ntawm txoj kev
- As a food additive
- Raws li tus desiccant thiab ziab khaub ncaws
- Siv hauv cov pob zeb sib tov rau kev nrawm ntawm kev pib daws teeb meem
Daim duab 01: Qhov tshwm sim ntawm Calcium Chloride (Anhydrous)
Txawm li cas los xij, qhov sib xyaw no muaj kev phom sij vim tias nws ua rau tawv nqaij. Ntxiv mus, kev noj cov calcium chloride tuaj yeem ua rau hypercalcemia. Thaum xav txog kev npaj, calcium chloride tuaj yeem tsim los ntawm cov txheej txheem Solvay; peb tuaj yeem tau txais qhov sib xyaw ua ke raws li cov khoom lag luam ntawm cov txheej txheem no. Tsis tas li ntawd, cov khoom tseem ceeb rau txoj kev Solvay yog limestone.
Calcium Chloride Dihydrate yog dab tsi?
Calcium chloride dihydrate yog ib qho inorganic hydrated compound uas muaj cov tshuaj formula CaCl2(H2O) 2 Cov molar mass ntawm no compound yog 111.56 g / mol. Thaum xav txog cov qauv ntawm cov khoom sib xyaw no, nws muaj ib qho calcium chloride molecule hauv kev koom tes nrog ob lub dej molecules. Lub melting point ntawm no compound yog 175 ° C thiab tom qab cua sov ntxiv, nws decomposes. Ntxiv mus, daim ntawv dihydrate no ib txwm tshwm sim raws li qhov tsis tshua muaj evaporate "sinjarite".
Qhov txawv ntawm Calcium Chloride thiab Calcium Chloride Dihydrate yog dab tsi?
Calcium chloride yog ib qho inorganic compound uas muaj CaCl2 while Calcium chloride dihydrate yog ib qho inorganic hydrated compound uas muaj cov tshuaj formula CaCl2 (H2O)2 Qhov sib txawv tseem ceeb ntawm calcium chloride thiab calcium chloride dihydrate yog calcium chloride yog anhydrous thaum calcium chloride dihydrate yog ib daim ntawv hydrated. ntawm calcium chloride. Tsis tas li ntawd, calcium chloride ib txwm tshwm sim los ntawm qhov tsis tshua muaj evaporate "sinjarite" lossis "antarcticite" thaum calcium chloride dihydrate tshwm sim li sinjarite.
Summary – Calcium Chloride vs Calcium Chloride Dihydrate
Calcium chloride yog ib qho inorganic compound uas muaj CaCl 2 hos Calcium chloride dihydrate yog ib qho inorganic hydrated compound uas muaj cov tshuaj formula CaCl2 (H2O)2Qhov sib txawv tseem ceeb ntawm calcium chloride thiab calcium chloride dihydrate yog tias calcium chloride yog anhydrous thaum calcium chloride dihydrate yog ib daim ntawv hydrated ntawm calcium chloride.
