Raws li UPAC " kev daws teeb meem yog ib qho kev sib cuam tshuam ntawm cov kuab tshuaj nrog cov kuab tshuaj, uas ua rau kom ruaj khov ntawm cov hom solute hauv cov tshuaj. " kev daws teeb meem tsis yog tshuaj tiv thaiv , thiab txuas ntxiv lub dissolution ntawm ntsev tsis yog ib tug tshuaj tiv thaiv , tab sis theem kev hloov.

Kuj paub, yog kev daws teeb meem yog hloov tshuaj?

Dissolving qab zib hauv dej yog ib qho piv txwv ntawm lub cev hloov . Vim li no: A tshuaj hloov tsim tawm tshiab tshuaj cov khoom. Yuav kom qab zib nyob rau hauv dej ua ib tug tshuaj hloov , ib yam dab tsi tshiab yuav xav tau. Cov tshuaj tuaj yeem hloov daim ntawv, tab sis tsis yog tus kheej.

Dab tsi yog qhov txawv ntawm dissociation thiab kev daws teeb meem? Kev daws, Kev daws teeb meem , thiab Kev tsis sib haum xeeb . Dissolution txhais tau hais tias tus txheej txheem ntawm dissolving los yog tsim ib tug daws. Cov kev sib tshuam nruab nrab cov solute hais thiab cov kuab tshuaj molecules hu ua kev daws teeb meem . A daws ion los yog molecule yog surrounded los ntawm hnyav.

Kuj tseem yuav paub, vim li cas cov kuab tshuaj xav tau rau cov tshuaj tiv thaiv tshuaj?

Hauv chemistry , kuab tshuaj cov teebmeem yog kev cuam tshuam ntawm a kuab tshuaj ntawm tshuaj reactivity los yog molecular koom haum. Cov kuab tshuaj tuaj yeem cuam tshuam rau solubility, stability thiab tshuaj tiv thaiv tus nqi thiab xaiv qhov tsim nyog kuab tshuaj tso cai rau thermodynamic thiab kinetic tswj ntawm ib tshuaj tiv thaiv.

Koj piav qhia txog kev sib cais li cas?

Kev daws yog tsim thaum ib yam khoom hu ua lub solute " yaj " rau hauv lwm yam khoom hu ua cov kuab tshuaj. Dissolving yog thaum tus solute tawg los ntawm ib tug loj siv lead ua ntawm molecules rau ntau me me los yog ib tug neeg molecules. Qhov kev tawg no yog tshwm sim los ntawm kev sib cuag nrog cov kuab tshuaj.
