Dej cov engineers zoo thiab cov kws kho mob tshwj xeeb feem ntau qhia txog qhov tseem ceeb ntawm calcium carbonate (mg CaCO 3 /l), thaum chemists qhia txog milliequivalents lossis molesper litre (meq/l lossis mmol/l). Kev coj ua los yog tshwj xeeb kev coj ua yog ib qho kev ntsuas ntawm lub peev xwm ntawm dej toconduct hluav taws xob tam sim no.

Ua ke, puas calcium carbonate ua hluav taws xob hauv dej?

Raws li solids, lawv ua tsis yog conductelectricity , mas ua yog li ob qho tib si thaum fused (melted) los yog hauv dej daws. Txawm li cas los xij, tsis yog tag nrho cov ionic compounds dej soluble, np. calcium carbonate . Molecularsolids yog tsim los ntawm cov molecules tuav ua ke los ntawm cov tsis muaj zog.

Qhov thib ob, yog calcium carbonate yog ib tug zoo conductor ntawm hluav taws xob? Raws li ib tug ruaj khov, calcium carbonate yog neeg pluag tus thawj coj piv rau cov hlau. Hauv kev daws raws li ions nws yog raws li zoo a tus thawj coj raws li feem ntau ntsev tov.

Hauv qhov no, yuav ua li cas thaum calcium carbonate tov nrog dej?

Calcium carbonate yuav teb nrog dej uas yog saturated nrog carbon dioxide los ua cov soluble calcium bicarbonate. Cov tshuaj tiv thaiv no tseem ceeb hauv theerosion ntawm carbonate pob zeb, tsim caverns, thiab coj mus rau hard dej hauv ntau thaj tsam.

Vim li cas CaCO3 insoluble hauv dej?

Vim calcium carbonate tsis yaj hauv dej , cov tub ntxhais kawm yuav tsum paub tias tsis yog txhua yam ionic yaj hauv dej . Piav tias nyob rau theem molecular, theions uas tsim calcium carbonate yog attracted heev rau ib leeg uas lub attraction los ntawm dej molecules tsis tuaj yeem rub lawv sib nrug.
