A homogeneous sib tov yog a sib tov nyob rau hauv uas muaj pes tsawg leeg yog uniform thoob plaws hauv lub sib tov . Cov dej ntsev piav saum toj no yog homogeneous vim yaj ntsev yog sib npaug faib thoob plaws dej ntsev qauv. Ib tug yam ntxwv ntawm sib tov yog tias lawv tuaj yeem muab cais rau hauv lawv cov khoom.
Kuj paub, yog dej ntsev yog homogeneous lossis heterogeneous sib tov?
Dej ntsev yog tsim los ntawm kev sib tov ntsev (NaCl) in dej . Nws yog ib homogeneous sib tov thiab a heterogeneous ib. Qhov sib txawv ntawm ob yog qhov concentration yog tib yam nyob txhua qhov chaw hauv cov ntaub ntawv ntawm a homogeneous sib tov , hos, cas a heterogeneous sib tov , qhov concentration txawv ntawm qhov chaw mus rau qhov chaw hauv ib sib tov.
Kuj Paub, yog vim li cas yuav tsum sib tov ua homogeneous? Feem ntau nws yooj yim rau confuse a homogeneous sib tov nrog cov khoom ntshiab vim tias lawv ob leeg sib xws. Txhua qhov kev daws teeb meem yuav raug txiav txim siab homogeneous vim hais tias cov khoom yaj muaj nyob rau hauv tib tus nqi thoob plaws hauv cov tshuaj. Ib tug yam ntxwv ntawm sib tov yog tias lawv tuaj yeem muab cais rau hauv lawv cov khoom.
Raws li qhov sib xyaw ua ke yog ntsev thiab dej?
Yog hais tias koj do ib diav ntsev rau hauv ib khob dej, ntsev yog qhov daws uas tau yaj. Dej yog qhov hnyav. Cov dej qab ntsev yog tam sim no a daws , los yog homogeneous sib tov, ntsev thiab dej. Thaum txawv cov pa yog tov, lawv ib txwm tsim ib daws.
Puas yog xim xim yog sib xyaw heterogeneous?
Xim yog a heterogeneous sib tov . Xim yog suav hais tias yog ib tug colloid, uas yog a heterogeneous sib tov qhov twg ib tug tshuaj yog dispersed nyob rau hauv lwm yam. A heterogeneous sib tov yog ib qho uas ntau tshaj ib yam yog pom thoob plaws hauv lub sib tov . Piv txwv ntawm homogeneous sib tov suav nrog tshuaj dawb, dej ntsev thiab cua.

Lub homogeneous sib tov muaj ib tug uniform muaj pes tsawg leeg thiab tsos. Cov tshuaj ib leeg uas tsim ib homogeneous sib tov tsis tuaj yeem pom qhov sib txawv. Ntawm qhov tod tes, ib qho sib tov sib xyaw ua ke muaj ob lossis ntau yam khoom uas tuaj yeem pom tau meej, thiab txawm tias sib cais yooj yim
Yuav ua li cas tshwm sim thaum aqueous tov ntawm sodium sulphate thiab barium chloride sib tov?
Thaum cov tshuaj aqueous ntawm sodium sulphate reacts nrog ib tug aqueous tov ntawm barium chloride, precipitate ntawm barium sulphate yog tsim thiab tom qab cov tshuaj tiv thaiv tshwm sim. ii. Yog hais tias cov reactants nyob rau hauv lub cev muaj zog, ces cov tshuaj tiv thaiv yuav tsis tshwm sim. Nws yog ib qho kev hloov pauv ob npaug nrog rau nag lossis daus
