Calcium carbonate muaj ib qho tsis tshua muaj solubility hauv dej ntshiab(15 mg / L ntawm 25 ° C), tab sis nyob rau hauv dej nag saturated nrog carbon dioxide, nws solubility nce vim lub tsim cov calcium bicarbonate ntau soluble.
Vim li cas CACO3 tsis yaj hauv dej?
Tsuas yog vim cov khoom siv hluav taws xob ntawm cov carbonate anion thiab calcium ion muaj zog heev kom kov yeej los ntawm kev daws los ntawm dej molecules.
Puas calcium carbonate soluble hauv dej?
Calcium carbonate tshwm li dawb, tsw ntxhiab hmoov lossis tsis muaj xim muaju. Xyaum insoluble hauv dej.
Yuav ua li cas thaum CACO3 yaj hauv dej?
tshuaj muaj zog
Calcium carbonate yuav react nrog dej uas saturated nrog carbon dioxide los ua cov calcium bicarbonate soluble. Cov tshuaj tiv thaiv no yog qhov tseem ceeb hauv kev yaig ntawm cov pob zeb carbonate, tsim cov qhov tsua, thiab ua rau cov dej tawv hauv ntau thaj tsam.
CaCO3 dissociate li cas?
1 Calcium carbonate. … Nws yog chemically ruaj khov mus txog 800 ° C thiab siab tshaj qhov kub no nws dissociates rau calcium oxide thiab carbon dioxide.
