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.

Kev pom kev lom neeg yog ib txoj hauv kev los saib cov teeb meem puas siab puas ntsws los ntawm kev kawm lub hauv paus rau tsiaj thiab tib neeg tus cwj pwm. Nws yog ib qho ntawm cov kev xav loj hauv kev puas siab puas ntsws thiab muaj xws li kev kawm lub hlwb, lub cev tsis muaj zog, lub paj hlwb, thiab caj ces
Puas yog kev sib xyaw cov khoom xyaw rau lub ncuav mog qab zib yog tshuaj lom neeg?
Cov ntaub ntawv yooj yim ntawm kev sib cais thiab sib xyaw yog suav tias yog kev hloov pauv ntawm lub cev, tab sis kev sib xyaw cov khoom xyaw ntawm lub ncuav mog qab zib tsis yog ib qho kev sib xyaw yooj yim. Kev hloov tshuaj pib tshwm sim thaum cov khoom xyaw sib xyaw, tsim cov tshuaj tshiab
Puas yog kev sib xyaw ntsev thiab kua txob yog lub cev lossis tshuaj lom neeg?
Piv txwv li, sib tov ntsev thiab kua txob tsim ib yam khoom tshiab yam tsis tau hloov cov tshuaj pleev ib ce ntawm ob qho tib si. Lawv kuj yog lub cev hloov pauv vim lawv tsis hloov qhov xwm txheej ntawm cov khoom
Puas yog nws ua tau rau ib qho kev sib npaug ntawm ob txoj kab sib npaug kom tsis muaj kev daws teeb meem piav qhia koj qhov laj thawj?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem.

Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
