Av carbonates tau piav raws li cov organic teeb meem stabilization tus neeg sawv cev, feem ntau yog vim tshuaj stabilization mechanisms. Hauv tshooj no, peb tsom mus rau lub luag haujlwm ntawm carbonates raws li indirect neeg sawv cev ntawm lub cev stabilization ntawm organic C los ntawm lawv cov kev cuam tshuam rau av qauv.
Sib piv, Dab tsi yog Dawb carbonates hauv av?
Dawb carbonates yog cov sib xyaw ua ke av cov khoom. Lawv tsim nyob rau hauv tej yam kev mob xws li nyob rau hauv qhuav huab cua qhov twg pH siab tshaj 7. Lawv kuj muaj nyob rau hauv ib co av profiles uas muaj niam txiv cov ntaub ntawv ua los ntawm carbonates (xws li limestone).
Ib tug kuj yuav nug, dab tsi yog calcium carbonate av? Calcium Carbonate (Limestone) Calcium carbonate , cov khoom tseem ceeb ntawm limestone, yog ib qho kev hloov kho dav siv los ua kom tsis muaj zog av acidity thiab khoom calcium (Ca) rau cov nroj tsuag noj zaub mov. Lo lus "txiv qaub" tuaj yeem xa mus rau ntau yam khoom, tab sis kev siv ua liaj ua teb feem ntau yog hais txog av limestone.
Raws li txoj cai, cov ntsiab lus ntawm cov av carbonate yog dab tsi?
CARBONATE . Inorganic carbonate hauv av tshwm sim feem ntau raws li sparingly soluble alkaline-lub ntiaj teb carbonates , calcite (CaCOs) thiab dolomite (CaMg(CO,),). Calcite feem ntau yog daim ntawv tseem ceeb hauv qhov chaw pedogenic (Doner & Lynn, 1977; Nelson, 1982).
Puas yog calcium carbonate zoo rau av?
Calcium carbonate yog ib yam khoom zoo heev rau kev nce pH ntawm av . Feem ntau (tsis yog tag nrho!) cov nroj tsuag ua tau zoo tshaj plaws hauv av nrog pH ntawm 5.5 thiab 6.5. Calcium carbonate tuaj yeem tshaj tawm thiab muab tso rau hauv av xav tau koob tshuaj alkalinity.

Cov mis rau polyatomic ion carbonate yog dab tsi?
Nqe lus piav qhia: Carbonate Ion yog polyatomic ion
Cov tshuaj tiv thaiv dab tsi yog calcium carbonate calcium oxide carbon dioxide?
Calcium carbonate tau kub siab kom txog thaum nws dhau los ua thermal decomposition los tsim calcium oxide thiab carbon dioxide. Cov calcium oxide (unslaked txiv qaub) yog yaj hauv dej los tsim calcium hydroxide (limewater). Bubbling carbon dioxide los ntawm qhov no ua ib qho kev ncua ntawm calcium carbonate
Dab tsi yog cov khoom ntawm phosphorous acid Dab tsi yog nws cov mis?
Phosphorous acid (H3PO3) tsim cov ntsev hu ua phosphites, kuj siv los txo cov neeg ua haujlwm. Nws yog npaj los ntawm dissolving tetraphosphorus hexoxide (P4O6) los yog phosphorus trichloride (PCl3) hauv dej
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
