Calcium carbonate muaj a solubility tsawg heev 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 ntawm ntau soluble calcium bicarbonate. Calcium carbonate yog qhov txawv ntawm qhov nws solubility nce raws li qhov kub ntawm cov dej txo.
YPuas yog calcium carbonate soluble hauv dej?

Yuav ua li cas thaum koj tso calcium carbonate hauv dej?
Calcium carbonate reacts nrog 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.
Koj txo calcium carbonate hauv dej li cas?
txiv qaub Softening
tshuaj nag lossis dausyog ib txoj hauv kev siv los ua kom dej muag. Cov tshuaj nquag siv yog txiv qaub (calcium hydroxide, Ca (OH) 2) thiab soda tshauv (sodium carbonate, Na2CO3). Txiv qaub yog siv los tshem tawm cov tshuaj uas ua rau carbonate hardness.
