I am looking for the answer to this question too. It seems to me that the two must be closely related. I am of the opinion (unsubstantiated at this point) that when the electronegativity difference between bonding atoms is in the 0.5-1.7 range it would make sense for the substance to be insoluble, as the forces holding the molecule together are then stronger than the hydrogen bonds of water. However, this is difficult to show as I cannot find electronegativities for polyatomic ions, and most insoluble salts contain them. If, however the atoms are held together by ionic bonds (electronegativities greater than 0.7), the ions dissociate easily in water.
