Nyob rau hauv cov tshuaj NaCl (dej-dej), cov kuab tshuaj yog dej. … Ib qho tshuaj aqueous yog ib qho tshuaj uas dej yog qhov hnyav. Cov tshuaj NaCl yog cov tshuaj aqueous. Cov tshuaj uas tsis yog-aqueous yog cov tshuaj uas dej tsis yog cov kuab tshuaj.
Vim li cas NaCl yog soluble hauv dej?
Thaum ntsev tov nrog dej, ntsev dissolves vim cov ntaub ntawv covalent ntawm cov dej muaj zog dua cov ionic bonds hauv cov ntsev molecules. … Cov dej molecules rub cov sodium thiab chloride ions sib nrug, rhuav cov ionic bond uas tuav lawv ua ke.
Vim li cas NaCl nruab nrab hauv cov tshuaj aqueous?
NaCl yog ntsev ntawm cov kua qaub HCl thiab muaj zog hauv paus NaOH. Nws tsis dhau hydrolysis vim tsis muaj cov tshuaj tiv thaiv ntawm ions ntawm ntsev NaCl nrog dej. Aqueous tov ntawm NaCl muaj tus lej sib npaug ntawm H + thiab OH- ions, yog li nws yog qhov nruab nrab hauv qhov xwm txheej.
NaCl aqueous puas yog lub hauv paus?
Cov ntsev uas yog los ntawm cov hauv paus muaj zog thiab muaj zog acids tsis hydrolyze. Cov pH yuav nyob nruab nrab ntawm 7. Halides thiab alkaline hlau dissociate thiab tsis cuam tshuam rau H+ vim cov cation tsis hloov H+ thiab cov anion tsis nyiam H+ los ntawm dej. Qhov no yog vim li cas NaCl yog ntsev nruab nrab.
Dab tsi ua rau cov dej sib xyaw ua ke?
Ib qho tshuaj aqueous yog dej uas muaj ib lossis ntau dua cov tshuaj yaj. Cov tshuaj yaj nyob rau hauv cov kua dej yuav yog cov khoom khib nyiab, gases, lossis lwm yam kua. … Solutecov khoom tuaj yeem yog atoms, ions, lossis molecules, nyob ntawm seb yam khoom uas tau yaj lawm. Daim duab 7.5.
