Nonpolar compounds tsis yaj nyob rau hauv dej Lub zog txaus nyiam uas ua haujlwm ntawm cov khoom nyob rau hauv ib qho nonpolar compound yog qaug zog dispersion zog. Thaum lwm tus polar kua xws li ethanol tov nrog dej, lawv tag nrho sib tov thiab yaj rau ib leeg. …
Yuav ua li cas yaj hauv cov tshuaj tsis muaj polar?
Polar/ionic solvents dissolve polar/ionic solutes thiab non-polar solvents dissolve non-polar solutes. Piv txwv li, dej yog cov kuab tshuaj polar thiab nws yuav yaj cov ntsev thiab lwm cov polar molecules, tab sis tsis yog polar molecules zoo li roj. Petrol yog cov kuab tshuaj uas tsis yog-polar thiab yuav yaj cov roj, tab sis yuav tsis tov nrog dej.
Yuav ua li cas yaj hauv cov kuab tshuaj tsis muaj polar?
Polar tshuaj zoo li yaj hauv cov kuab tshuaj polar, thiab nonpolar cov tshuaj yaj hauv cov kuab tshuaj tsis muaj polar. Thaum ib tug solute dissolves nyob rau hauv ib tug hnyav tus neeg hais txog ntawm cov kuab tshuaj cais los ntawm lawv cov neeg nyob ze thiab txav ntawm qhov chaw ntawm cov kuab tshuaj.
Puas tsis muaj polar yaj hauv dej?
Nonpolar molecules tsis yaj yooj yim hauv dej. Lawv tau piav raws li hydrophobic, lossis dej ntshai. Thaum muab tso rau hauv qhov chaw ib puag ncig, xws li dej, tsis muaj polar molecules lo ua ke thiab tsim ib daim nyias nyias, tiv thaiv dej los ntawm ib puag ncig cov molecule.
Yuav ua li cas ionic compounds dissolve nyob rau hauv nonpolar tshuaj?
Ionic compounds yog soluble hauv polar solvents thiab insoluble hauv non-polar solvents. … Cov kuab tshuaj uas tsis yog-polar zoo li kerosene, benzene tsis muaj peev xwm ntawm cov khoom tawg ionic vim lawv tsis tuaj yeem txo cov quab yuam ntawm kev nyiam ntawm cov ions.
