Solubility yog qhov ntsuas ntawm qhov ntau npaum li cas yam khoom yuav yaj nyob rau hauv ib tug muab ntim ntawm a ua kua . Cov ua kua hu ua kuab tshuaj. Lub solubility ntawm ib tug roj nyob ntawm siab thiab kub.

Yog li ntawd, lo lus scientific siv los piav txog ib yam khoom uas yuav tsis yaj?

Hauv qhov piv txwv no, qab zib yog cov kua dej thiab dej yog qhov hnyav. Ib tug sib tov uas a tshuaj tsis yaj hauv dej yog hu ua suspension thiab yam khoom hais tias yog insoluble.

Tom qab, lo lus nug yog, dab tsi cov khoom yog soluble nyob rau hauv dej? Ionic tshuaj yog feem ntau soluble feem ntau nyob rau hauv polar solvents; qhov siab dua lub lattice zog, lub polar ntau dua qhov hnyav yuav tsum tau kov yeej lub lattice zog thiab yaj tus yam khoom.

Ib yam li ntawd, ib tug yuav nug, lub sij hawm twg yog muab rau cov khoom uas tuaj yeem yaj hauv cov kua?

A khoom dissolves nyob rau hauv ib tug kua thaum nws tov tag nrog cov ua kua . Tej yam uas yaj hu ua solutes thiab ua kua hauv lawv yaj yog hu ua cov kuab tshuaj los tsim cov tshuaj. Cov khoom muaj zog polar yooj yim nyiam cov dej molecules. Cov dej molecules nyob ib puag ncig ntawm cov kuab tshuaj.

Koj hu dab tsi uas yaj hauv dej?

Dej yog ib qho hnyav, txhais tau tias nws yog kua uas yaj tshuaj. Ib yam khoom ntawd yaj yog hu ua lub solute, thiab qhov sib tov tsim thaum cov kuab tshuaj thiab solute tag ua ke thiab ua tsis cais yog hu ua kev daws teeb meem.
