why are some substances soluble and some insoluble?

-water is a polar, covalent molecule

-dipoles in water are attracted to anions or cations respectively

-bent shape allows dipoles to surround anions/cations

-the dipole-ion attraction must be > than the electrostatic attraction between the ions in the compound
