Kev daws teeb meem, kev daws teeb meem thiab kev sib txawv ntawm qhov sib txawv
Txhais los ntawm International Union ntawm Ntshiab thiab Kev Siv Tshuaj (IUPAC), kev daws teeb meem yog hais txog kev sib cuam tshuam ntawm cov solute thiab cov kuab tshuaj uas ua kom lub zog nyob hauv kev daws teeb meem. Nyob ntawm seb cov ions raug puag ncig los ntawm cov tshuaj lwg me hauv cov kuab tshuaj lossis tsim ib qho nyuaj, nws tuaj yeem siv los qhia lub xeev ntawm cov kuab tshuaj. (Xa mus rau Solvaton plhaub) Lub tswvyim ntawm kev daws teeb meem tseem tuaj yeem siv rau cov ntaub ntawv tsis txaus ntseeg xws li kev ua haujlwm pab pawg solvation nyob rau saum npoo ntawm ion pauv resins.
Kev Ua Zoo, kev daws teeb meem thiab kev daws teeb meem thiab kev daws teeb meem yog qhov txawv. Ib tug txheej txheem uas yaj mus rau hauv cov kinetics tshuaj lom neeg, muaj ntau yam los ntawm nws tus nqi. Thaum qhov kev tshem tawm tus nqi thiab cov nag lossis daus sib npaug, cov solubility nce mus txog lub xeev ntawm qhov sib npaug ntawm qhov sib npaug.
Cov koog tuaj yeem nkag siab zoo dua qhov sib txawv ntawm peb. Kev sib koom tes muaj peev xwm piav qhia los ntawm ib qho nyuaj sib npaug nrog cov naj npawb sib xyaw. Chav tsev ntawm kev tshem tawm yog mol / s, thiab chav tsev ntawm kev daws teeb meem yog mol / kg.
Qhov sib txawv hauv kev daws teeb meem tseem nyob hauv qhov tseeb tias liquefaction nrog cov kev hloov pauv hauv kev siv tshuaj lom neeg. Piv txwv li, zinc tsis tuaj yeem tiv thaiv nrog hydrochloric acid, tab sis nws tuaj yeem tsim cov soluble zinc chloride ntsev los ntawm kev fab tshuaj.
