Qhov sib txawv tseem ceeb ntawm cob alt chloride thiab calcium chloride yog cob alt chloride muaj cob alt cation bonded rau chloride anion, thiab nws yog ntuj xiav xim, whereas calcium chloride muaj calcium cation bonded rau chloride anion thiab nws. yog xim dawb.
Cob alt chloride yog ntsev ntawm cob alt, thaum calcium chloride yog ib qho inorganic compound uas muaj cov tshuaj formula CaCl2. Ob lub tebchaw no yog cov ionic compounds uas muaj tshuaj lom neeg thiab lub cev sib txawv. Lawv kuj txawv ntawm qhov tsos.
Cob alt Chloride yog dab tsi?
Cob alt chloride tuaj yeem piav qhia tias yog ntsev ntawm cob alt. Nws yog ib qho inorganic compound uas muaj cov tshuaj formula CoCl2. Daim ntawv hydrated ntawm no compound yog ib tug hexahydrate compound uas muaj ib tug cob alt chloride ntsev molecule attracted rau rau dej molecules.
CoCl2 6H2O yog cob alt chloride hexahydrate uas muaj cob alt chloride slat molecules attracted rau rau dej molecules. Daim ntawv hydrated no muaj xim liab-liab, thiab nws yog crystalline compound. Cov molar loj ntawm cov tshuaj no yog 237.93 g / mol. Nws qhov ceev yog li 1.924 g / cm3.
Anhydrous cob alt chloride yog daim ntawv tsis muaj dej ntawm cob alt chloride ntsev. Nws tsis muaj dej rau crystallization. Nws muaj lub ntuj xiav xim. Cov molar loj ntawm cov tshuaj no yog 129.84 g / mol. Nws melting point yog 735 ◦C. Lub compound muaj hexagonal geometry.
Calcium Chloride yog dab tsi?
Calcium chloride tuaj yeem piav qhia tias yog ib qho inorganic compound uas muaj cov tshuaj formula CaCl2. Nws yog chloride ntsev ntawm calcium. Nws pom tau tias cov khoom no muaj nyob rau hauv cov xim dawb-xim crystalline khoom ntawm chav tsev kub. Tsis tas li ntawd, cov khoom siv calcium chloride yog cov dej-soluble heev.
Calcium chloride feem ntau hu ua hydrated tshuaj; tus naj npawb ntawm cov dej molecules uas muaj feem xyuam nrog ib qho calcium chloride molecule tuaj yeem yog 0, 1, 2, 4, lossis 6. Feem ntau, cov hydrates no yog ib qho tseem ceeb ntawm cov tshuaj de-icing thiab ua cov tshuaj tiv thaiv plua plav. Tsis tas li ntawd, ib qho anhydrous CaCl2 cov khoom muaj txiaj ntsig zoo li desiccant vim nws qhov xwm txheej hygroscopic.
Peb tuaj yeem npaj calcium chloride los ntawm limestone ua cov khoom lag luam ntawm cov txheej txheem Solvay. Cov txheej txheem Solvay yog txoj kev tsim cov sodium carbonate, qhov twg calcium chloride forms nrog rau sodium carbonate. Cov tshuaj tiv thaiv muaj sodium chloride thiab calcium carbonate (los ntawm limestone). Txawm li cas los xij, peb tuaj yeem ua cov tshuaj no los ntawm kev ua kom huv ntawm brine tov.
Feem ntau, calcium chloride yog suav tias yog cov tshuaj tsis muaj tshuaj lom. Txawm li cas los xij, vim nws cov cuab yeej hygroscopic, daim ntawv anhydrous ntawm qhov sib xyaw no tuaj yeem ua rau muaj kev phom sij. Nws tuaj yeem ua rau tawv nqaij los ntawm desiccating daim tawv nqaij moist.
Qhov txawv ntawm Cob alt Chloride thiab Calcium Chloride yog dab tsi?
Cob alt chloride tuaj yeem piav qhia tias yog ntsev ntawm cob alt. Calcium chloride tuaj yeem piav qhia tias yog ib qho inorganic compound uas muaj cov tshuaj formula CaCl2. Qhov sib txawv tseem ceeb ntawm cob alt chloride thiab calcium chloride yog cob alt chloride muaj cob alt cation bonded rau chloride anion, thiab nws yog ntuj xiav xim, whereas calcium chloride muaj calcium cation bonded rau chloride anion thiab nws yog xim dawb.
Cov duab hauv qab no nthuav tawm qhov sib txawv ntawm cob alt chloride thiab calcium chloride hauv daim ntawv tabular rau ib sab kev sib piv.
Summary – Cob alt Chloride vs Calcium Chloride
Txawm hais tias cov ntsiab lus calcium chloride thiab cob alt chloride suab zoo ib yam, lawv yog ob qho sib txawv kiag li. Qhov sib txawv tseem ceeb ntawm cob alt chloride thiab calcium chloride yog cob alt chloride muaj cob alt cation bonded rau chloride anion, thiab nws muaj lub ntuj xiav xim, whereas calcium chloride muaj calcium cation bonded rau chloride anion thiab nws yog dawb.
