Piv txwv . stirring qab zib rau hauv dej yog ib qho piv txwv ntawm dissolving . Cov qab zib yog tus solute, thaum tus dej yog tus kuab tshuaj. Dissolving ntsev hauv dej yog ib qho piv txwv ntawm kev tawg ntawm ib qho ionic compound.

Hais txog qhov no, dab tsi yog ib yam dab tsi uas yuav yaj tau?

Tej yam xws li ntsev, suab thaj thiab kas fes yaj hauv dej. Lawv yog soluble . Lawv feem ntau yaj sai dua thiab zoo dua hauv dej sov lossis dej kub. Kua txob thiab xuab zeb yog insoluble, lawv yuav tsis yog yaj txawm nyob hauv dej kub.

Tom qab, lo lus nug yog, dab tsi dissolving zoo li? Cov piv txwv feem ntau ntawm yaj koom nrog ib qho khoom thiab ua kua, feem ntau yog dej. Thaum ib tug khov yaj cov khoom (solute) thiab cov kua (solvent) tsim ib tug heev intimate sib tov hu ua ib tug tov.
