Qhov Tseem Ceeb Qhov txawv - Ionic Khoom vs Cov Khoom Solubility
Ob yam khoom ionic thiab cov khoom solubility qhia tib lub tswv yim ntawm cov khoom ntawm ntau hom ionic hauv kev daws teeb meem. Qhov sib txawv tseem ceeb ntawm cov khoom ionic thiab cov khoom solubility yog cov khoom ionic yog cov khoom ntawm ions nyob rau hauv ib qho unsaturated los yog saturated tov whereas solubility khoom yog cov khoom ntawm ions nyob rau hauv saturated daws.
Cov khoom lag luam solubility yog ib daim ntawv ntawm cov khoom ionic. Cov khoom ionic thiab cov khoom solubility sib txawv ntawm ib leeg raws li hom kev daws teeb meem.
Ionic khoom yog dab tsi?
Cov khoom ionic yog cov khoom lag luam ntawm ntau hom ionic nyob rau hauv ib qho saturated los yog unsaturated tov. Thaum tsuas yog cov kev daws teeb meem saturated raug txiav txim siab, cov khoom ionic hu ua cov khoom solubility. Lub sij hawm ionic khoom siv tau rau txhua hom kev daws teeb meem.
Cov Khoom Solubility yog dab tsi?
Solubility khoom yog qhov sib npaug tas li rau cov tshuaj lom neeg cov tshuaj tiv thaiv uas cov khoom ionic dissolves kom tawm los nws cov ions hauv cov tshuaj. Lub sij hawm solubility khoom yog siv rau saturated daws nkaus xwb. Solubility khoom yog qhia los ntawm Ksp. Cia peb xav txog ib qho piv txwv;
Ag+(aq) + Cl–(aq)→ AgCl(s)
Yog tias cov tshuaj yog saturated los ntawm AgCl (silver chloride), muaj qhov sib npaug ntawm cov hom soluble ionic thiab AgCl precipitate. Cov khoom solubility ntawm cov tshuaj no tuaj yeem muab tau raws li hauv qab no, Ksp=[Ag+(aq)][Cl– (aq)
Rau ib qho kev daws teeb meem (saturated), cov khoom solubility yog cov khoom ntawm ionic hom tsa rau hauv lawv cov stoichiometric coefficient. Rau cov piv txwv saum toj no, cov stoichiometric coefficients rau Ag+ thiab Cl– ions yog 1. Yog li ntawd, cov concentrations ntawm cov ions tau tsa rau hauv 1.
Qhov me dua cov khoom solubility ntawm ib yam khoom, ces txo cov solubility ntawm cov khoom ntawd. Qhov ntawd yog vim cov khoom solubility muab pes tsawg hom ionic yaj nyob rau hauv cov tshuaj ntawd. Yog hais tias tus nqi ntawm ionic hom yog me ntsis, nws qhia tau hais tias cov khoom tsis zoo-soluble nyob rau hauv cov kuab tshuaj. Ces cov khoom solubility kuj tsis tshua muaj nqi.

Ib qho tseem ceeb cuam tshuam rau cov khoom solubility ntawm cov khoom yog kub. Thaum qhov kub ntawm cov tshuaj yog nce, tus nqi ntawm solutes yaj nyob rau hauv uas yuav yaj nyob rau hauv qhov kev daws yog nce; uas txhais tau tias, lub solubility ntawm ib tug solute yog nce. Qhov no ua rau kom nce cov khoom solubility. Yog li ntawd, cov khoom muaj cov khoom sib txawv ntawm qhov sib txawv ntawm qhov kub thiab txias.

Summary – Ionic khoom vs Solubility khoom
Ionic khoom thiab cov khoom solubility yog ob nqe lus uas qhia tib lub tswv yim ntawm cov khoom ntawm hom ionic hauv kev daws teeb meem. Qhov txawv ntawm cov khoom ionic thiab cov khoom solubility yog cov khoom ionic yog cov khoom ntawm ions nyob rau hauv ib qho unsaturated los yog saturated tov whereas solubility khoom yog cov khoom ntawm ions nyob rau hauv saturated daws.
