Koj puas ntxiv cov kuab tshuaj rau cov kuab tshuaj?
Mov kom huv si kom yaj lub solute Thaum cov kuab tau yaj lawm, ntxiv cov kuab tshuaj uas tseem tshuav los ua cov tshuaj uas xav tau ntim thiab sib tov kom huv si. Piv txwv li, ua 0.5 Litres ntawm 0.5 molar NaCl: … Ua ib qho kev daws teeb meem ntawm ib qho concentration ntawm cov tshuaj hauv Tshuag yog hu ua dilution .
Thaum cov kuab tshuaj evaporates dab tsi tshwm sim rau qhov concentration ntawm cov tshuaj?
Qhov no txhais tau hais tias yog tias koj cov kuab tshuaj evaporating thiab qhov kub thiab txias tsis tu ncua, ces solute yuav precipitate tawm ntawm cov tshuaj.
