This is called hydration. Now remember, light dissolves like so. Polar molecules dissolve polar molecules and nonpolar molecules will dissolve other nonpolar molecules. Nonpolar will not be able to dissolve polar, and that's because they won't be able to overcome the large dipole moments of the polar molecules. And these dipole moments come from large differences in electronegativity. Now, salvation is the process of breaking down ionic compounds, bipolar compounds such as H 20.
