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.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Puas yog h2co3 precipitate?
[1] Tsim cov pa roj. Muaj qee qhov sib txuas uas tsis ruaj khov thiab decompose rau dej thiab roj. Peb hom yog H2CO3, H2SO3 thiab NH4OH. "Low solubility" txhais tau hais tias tsawg heev ntawm cov khoom dissolves nyob rau hauv dej, yog li feem ntau ntawm cov ntaub ntawv raws li ib tug precipitate
Yuav ua li cas koj precipitate silver?
Sau lub tog raj kheej txog ib nrab ntawm cov tshuaj sodium chloride. Ntxiv ob peb droppers uas muaj cov nyiaj nitrate tov rau lub tog raj kheej. Tam sim ntawd ib daim ntawv dawb precipitate. Silver nitrate yog ib qho muaj zog oxidizer, tab sis cov tshuaj yog dilute zoo
Puas yog lead phosphate yog precipitate?
Lead (II) phosphate yog insoluble hauv dej thiab cawv tab sis soluble hauv HNO3 thiab tau kho alkali hydroxides. Thaum cov hlau lead (II) phosphate yog rhuab rau decomposition nws emits cov pa phem heev uas muaj Pb thiab POx. Lead (II) phosphate. Cov npe tshuaj formula Pb3(PO4)2 Molar mass 811.54272 g/mol Zoo li hmoov dawb ceev 6.9 g/cm3
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
