Do molecular substances dissolve in water
WebWater molecules are polar and, like small magnets, they attract the molecules of other polar substances. If this attraction is strong enough, the other molecules can break apart, and those substances will dissolve. SCIENCE . Biology. Cells; Molecular; Microorganisms; Genetics; Human Body ... WebFor example, nonpolar molecular substances, like hydrocarbons, are likely to be insoluble in water. Polar substances are not likely to dissolve to a significant degree in nonpolar solvents. For example, ionic compounds are insoluble in hexane. It is more difficult to predict the solubility of polar molecular substances than to predict the ...
