Cov kws tshawb fawb tshwj xeeb yog xav paub txog aragonite, uas yog tsim los ntawm ntau qhov chaw kub thiab muaj xyoob ntoo corals, dej txias corals, pteropods thiab qee cov molluscs. Nws yog ntau dua soluble dua calciteCov kab mob loj hlob ntawm cov plhaub thiab pob txha pob txha yooj yim dua thaum cov carbonate ions hauv dej muaj ntau - nws yog supersaturated.
Puas yog calcite ntau soluble dua aragonite?
Aragonite, calcite's orthorhombic polymorph, yog kwv yees li 1.5 npaug ntau dua soluble dua calcite. … Nyob rau hauv lub ntiaj teb kub saum npoo av thiab siab, yog li ntawd, ntau hom carbonate mineral muaj ib tug hierarchy ntawm solubility, nrog magnesian calcite soluble tshaj plaws.
Vim li cas aragonite tsis ruaj khov dua li calcite?
Calcite thiab aragonite yog polymorphs ntawm calcium carbonate. Qhov sib txawv tseem ceeb ntawm calcite thiab aragonite yog qhov siv lead ua ntawm calcite yog trigonal, hos cov siv lead ua ntawm aragonite yog orthorhombic. Ntxiv mus, calcite ruaj khov dua aragonite.
Vim li cas calcite insoluble?
Calcite NW nyuam qhuav soluble hauv dej Tus cuam tshuam ntawm qhov kub ntawm solubility tsawg. Txawm li cas los xij, yog tias dej muaj CO 2, solubility ntawm calcite nce ntau vim tias tsim cov carbonic acid uas yuav ua rau tsim cov calcium bicarbonate, Ca(HCO 3.)2
Dab tsi yog qhov txawv ntawm calcite thiab aragonite?
Calcium carbonate tuaj yeem siv los ntawm ob qhov sib txawv: Calcite yog daim ntawv ruaj khov, whereas aragonite yog metastable: Sij hawm dhau mus, lossis thaum tshav kub, nws tuaj yeem hloov mus rau hauv calcite..
