A nag lossis daus yog hom tshuaj tiv thaiv nyob rau hauv uas ob soluble ntsev nyob rau hauv aqueous tov ua ke thiab ib tug ntawm cov khoom yog ib tug insoluble ntsev hu ua ib tug nag xob nag cua . Kuj, a nag xob nag cua tuaj yeem tsim nyob rau hauv qee yam mob, tab sis tsis yog lwm tus.

Tsis tas li lo lus nug yog, dab tsi yog qhov dej nag hauv chemistry?

Hauv chemistry , a nag xob nag cua yog ib yam khoom insoluble uas tawm los ntawm cov kua. Qhov tshwm sim ntawm cov khoom insoluble los ntawm kev daws yog hu ua nag lossis daus . Feem ntau cov nag xob nag cua tshwm sim raws li kev ncua. Precipitates tuaj yeem tsim tau thaum ob cov ntsev soluble hnov mob hauv kev daws teeb meem los tsim ib lossis ntau yam khoom tsis zoo.

Qhov thib ob, qhov piv txwv ntawm kev tsim cov nag lossis daus yog dab tsi? Ib piv txwv Cov tshuaj tiv thaiv nag lossis daus: Aqueous silver nitrate (AgNO3) yog ntxiv rau cov tshuaj uas muaj poov tshuaj chloride (KCl), nag lossis daus ntawm cov khoom dawb, nyiaj chloride (AgCl), tau pom. (Zumdahl, 2005) Cov nyiaj chloride (AgCl) muaj tsim ib tug khoom, uas yog pom raws li ib tug nag xob nag cua.

Tsis tas li ntawd, vim li cas cov dej nag hauv cov tshuaj tiv thaiv?

Dej nag cov tshuaj tiv thaiv tshwm sim thaum cations thiab anions hauv aqueous tov ua ke rau daim ntawv ib qho insoluble ionic khoom hu ua a nag xob nag cua . Seb puas yog ib tug tshuaj tiv thaiv tshwm sim ua tau txiav txim siab los ntawm kev siv cov cai solubility rau cov ionic solids.

Ua piv txwv nag lossis daus yog dab tsi?

Ib txhia piv txwv ntawm nag lossis daus yog nag, lawg, nag, thiab daus. Condensation yog thaum huab cua txias hloov dej vapor rov ua kua thiab ua rau huab.
