Vim li cas cov kuab tshuaj yaj hauv dej?
Ib qho hnyav yog ib yam khoom uas tuaj yeem yaj lwm cov molecules thiab cov tebchaw, uas yog hu ua solutes. … Vim nws qhov polarity thiab muaj peev xwm tsim cov ntawv cog lus hydrogen, dej ua rau cov kuab tshuaj zoo heev, txhais tau tias nws tuaj yeem yaj ntau hom molecules.
Yuav ua li cas thaum cov kuab tshuaj yaj hauv dej?
Ib tshuaj yog tsim thaum ib yam khoom hu ua solute "dissolves" rau lwm yam khoom hu ua hnyav. Dissolving yog thaum lub solute breaks nce los ntawm ib tug loj siv lead ua ntawm molecules mus rau ntau me me los yog ib tug molecules. … Tam sim no nws tsuas yog nyob ib puag ncig los ntawm cov dej molecules es tsis txhob kho rau cov ntsev ntsev.
Yuav ua li cas yaj hauv dej?
Yam xws li ntsev, qab zib thiab kas fes yaj hauv dej. Lawv yog cov soluble. Lawv feem ntau yaj sai dua thiab zoo dua hauv dej sov lossis dej kub. Kua txob thiab xuab zeb yog insoluble, lawv yuav tsis yaj txawm nyob rau hauv dej kub.
Puas cov kuab tshuaj dissolves?
Cov kuab tshuaj yog cov khoom uas tau yaj, hos cov kuab tshuaj yog qhov nruab nrab. Cov kev daws teeb meem tuaj yeem tsim nrog ntau yam sib txawv thiab cov qauv ntawm cov kuab tshuaj thiab cov kuab tshuaj. Peb paub ntau hom kev daws teeb meem.

Piv txwv li, ua 0.5 Litres ntawm 0.5 molar NaCl: … Ua ib qho kev daws teeb meem ntawm ib qho concentration ntawm cov tshuaj hauv Tshuag yog hu ua dilution .
Thaum twg cov tshuaj yaj hauv dej cov nyhuv yog li cas?
Raws li txhua lub cev molecule maj mam tawg, cov dej molecules nyob ib puag ncig nws, thiab nws ntws mus rau hauv cov tshuaj Yog tias cov kua dej yog cov khoom, cov txheej txheem no maj mam tshwm sim. Cov molecules saum npoo yog thawj zaug mus, nthuav tawm cov hauv qab rau cov dej molecules uas tseem tsis tau sib txuas .
Thaum cov kuab tshuaj evaporates dab tsi tshwm sim rau qhov concentration ntawm cov tshuaj?
Qhov no txhais tau hais tias yog tias koj cov kuab tshuaj evaporating thiab qhov kub thiab txias tsis tu ncua, ces solute yuav precipitate tawm ntawm cov tshuaj. Qhov concentration ntawm cov tshuaj yuav tseem nyob rau ntawm nws qhov siab tshaj plaws raws li koj muaj kev txhawj xeeb nrog cov nyiaj solute yaj .
Puas dej ntws mus rau cov kuab tshuaj?
Cov ntsev thiab suab thaj hauv cov tshuaj yuav tawm mus deb ntawm thaj chaw uas muaj siab rau hauv cov tshuaj ib puag ncig. Qhov no yog hu ua yooj yim diffusion. Dej kuj diffuses deb ntawm thaj chaw ntawm cov dej dawb siab concentration mus rau thaj tsam ntawm ntau cov kua qaub .
