Qhov sib txawv tseem ceeb ntawm hom thiab theem hauv kev daws yog cov hom kev daws teeb meem yog hais txog cov tshuaj lom neeg muaj nyob hauv cov tshuaj hos theem hauv cov tshuaj yog hais txog ntau hom tshuaj muaj nyob hauv cov tshuaj.
A tov yog sib tov ntawm cov kuab tshuaj thiab ib tug solute(s). Solutes yog yaj nyob rau hauv cov kuab tshuaj. Qee cov kuab tshuaj yaj hauv cov kuab tshuaj raws li lawv yog thaum lwm tus yaj los ntawm ionization. Yog li ntawd, cov hom muaj nyob rau hauv cov tshuaj nyob ntawm seb lub peev xwm ionization ntawm cov compound nyob rau hauv cov kuab tshuaj. Muaj ob hom kev daws teeb meem raws li homogeneous kev daws teeb meem thiab cov kev daws teeb meem heterogeneous, nyob ntawm theem ntawm qhov teeb meem.
Dab tsi yog Hom Tshuaj hauv Kev daws?
Cov kab mob hauv cov tshuaj yog hais txog cov tshuaj lom neeg uas tsim los ntawm kev sib cais ntawm cov kuab tshuaj hauv cov kuab tshuaj thaum tsim cov tshuaj. Qee hom yaj hauv cov kuab tshuaj zoo li lawv. Piv txwv li, glucose dissolution tsim cov kua qabzib aqueous, uas muaj cov piam thaj molecules uas tsis tau hloov pauv. Ntawm no, hom tshuaj hauv cov tshuaj yog cov piam thaj molecules.
Qee zaum, ionic compounds yaj hauv cov kuab tshuaj los ntawm ionization. Qhov ntawd txhais tau tias; Lub compound dissociates rau hauv nws cov ionic Cheebtsam thaum dissolution nyob rau hauv cov kuab tshuaj. Nyob rau hauv cov ntaub ntawv no, cov tshuaj muaj nyob rau hauv cov tshuaj yog cov ionic Cheebtsam, tsis yog cov molecule uas yaj. Yog li, cov tsiaj hauv cov tshuaj tuaj yeem sib txawv nyob ntawm qhov muaj peev xwm ionization ntawm cov kua.
Daim duab 01: Ionic Hom hauv Dej
Thaum piav qhia txog cov khoom ntawm cov tshuaj, nws yog ib qho tseem ceeb kom paub cov tshuaj muaj nyob hauv cov tshuaj. Piv txwv li, thaum peb tab tom qhia qhov concentration ntawm ib qho kev daws, peb feem ntau xa mus rau qhov concentration ntawm cov kuab tshuaj yaj los yog ions. Tsis tas li ntawd, qhov kub ntawm cov tshuaj, solubility ntawm lwm cov tshuaj nyob rau hauv ib qho kev daws, thiab ntau lwm yam kev daws teeb meem yog nyob ntawm seb hom muaj nyob rau hauv cov tshuaj.
Phase hauv Kev daws yog dab tsi?
Phase hauv kev daws yog hais txog qhov muaj lossis tsis muaj ib lossis ntau theem ntawm cov teeb meem hauv tib txoj kev daws teeb meem. Ntawm no, peb tuaj yeem faib cov kev daws teeb meem ua ob hom kev daws teeb meem homogeneous thiab heterogeneous daws.
Daim duab 02: Mis yog ib qho tshuaj Heterogeneous
Ib homogeneous tov kuj hu ua ib theem kev daws vim nws muaj tag nrho nws cov teeb meem nyob rau hauv tib theem. Qhov ntawd txhais tau tias, cov kuab tshuaj thiab cov kuab tshuaj nyob hauv tib theem, thiab peb tsis tuaj yeem soj ntsuam cov theem sib txawv hauv cov kev daws teeb meem no. Hauv qhov sib piv, cov kev daws teeb meem heterogeneous yog ntau txoj kev daws teeb meem. Qhov ntawd yog; cov kev daws teeb meem no muaj ob lossis ntau theem hauv tib txoj kev daws teeb meem. Piv txwv li, emulsions muaj cov kua thiab cov theem nyob rau hauv tib cov tshuaj.
Dab tsi yog qhov txawv ntawm hom thiab theem hauv kev daws?
Qhov sib txawv tseem ceeb ntawm hom thiab theem hauv kev daws yog cov hom kev daws teeb meem yog hais txog cov tshuaj lom neeg muaj nyob hauv cov tshuaj, hos theem hauv cov tshuaj yog hais txog cov qauv sib txawv ntawm cov tshuaj muaj nyob hauv cov tshuaj. Ntxiv mus, molecules los yog ions yog cov khoom ntawm ib hom nyob rau hauv ib tug tov, whereas kua thiab cov theem yog cov Cheebtsam ntawm ib hom nyob rau hauv ib tug tov.
Cov infographic hauv qab no qhia txog qhov sib txawv ntawm hom thiab theem hauv kev daws teeb meem.
Summary – Hom vs Phase hauv kev daws
A tov yog sib tov ntawm cov kuab tshuaj thiab ib tug solute(s). Solute (s) yog yaj nyob rau hauv cov kuab tshuaj. Cov hom hauv kev daws teeb meem thiab theem hauv kev daws yog cov ntsiab lus tseem ceeb thaum nthuav tawm cov khoom ntawm kev daws teeb meem. Qhov sib txawv tseem ceeb ntawm hom thiab theem hauv kev daws yog cov hom kev daws teeb meem yog hais txog cov khoom siv tshuaj lom neeg tam sim no hauv cov tshuaj, hos theem hauv kev daws yog hais txog cov qauv sib txawv ntawm cov tshuaj muaj nyob hauv cov tshuaj.
