Vim li cas caco3 tsis soluble hauv dej?
Tsuas yog vim cov electrostatic bonds ntawm cov carbonate anion thiab calcium ion muaj zog heev uas yuav tsum tau kov yeej los ntawm kev daws los ntawm dej molecules.
Yuav caco3 yaj?
Cov calcium carbonate yuav yaj hauv cov kua qaub ua CO 2 roj . Nws yuav tsis yaj hauv dej ntshiab. Ksp rau calcium carbonate hauv dej yog 3.4 x 10-9.
Yuav ua li cas thaum caco3 yaj hauv dej?
CaCO3(s) → CaO(s) + CO2(g) Calcium carbonate reacts with dej uas saturated nrog carbon dioxide los ua cov soluble calcium bicarbonate. 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.
