Video piav. Teb. Hardness hauv dej yog vim yaj sulphate, chlorides thiab bicarbonates ntawm calcium thiab magnesium. Thaum cov dej zoo li no siv los ntxuav khaub ncaws nrog xab npum (e., sodium stearate) a curdy precipitate ntawm calcium thiab magnesium ntsev yog tsim.

Tsuas yog li ntawd, Curdy txhais li cas?

adjective, curd·i·er, curd·i·est. zoo li curd; tag nrho los yog muaj curd; coagulated.

Ib yam li ntawd, dab tsi yog precipitate nyob rau hauv cov tshuaj tiv thaiv? A nag lossis daus hais txog kev tsim cov ntsev insoluble thaum ob txoj kev daws teeb meem uas muaj cov ntsev soluble ua ke. Cov ntsev insoluble uas ntog tawm ntawm kev daws yog hu ua nag xob nag cua , li no cov cov tshuaj tiv thaiv npe. Kev tiv thaiv nag lossis daus tuaj yeem pab txiav txim seb muaj ntau yam ions hauv kev daws teeb meem.

Ib sab saum toj no, dab tsi yog ib qho piv txwv ntawm precipitate?

Ib piv txwv ntawm a nag lossis daus Cov tshuaj tiv thaiv: Aqueous silver nitrate (AgNO3) yog ntxiv rau cov tshuaj uas muaj potassium chloride (KCl), cov nag lossis daus Ntawm cov khoom dawb, nyiaj chloride (AgCl), raug pom. (Zumdahl, 2005) Cov nyiaj chloride (AgCl) tau tsim cov khoom, uas tau pom tias yog nag xob nag cua.

Cov dej nag zoo li cas?

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 qhov kub ntawm cov tshuaj txo qis.
