1. Solubility

   • Solutes dissolve best in solvents with similar Intermolecular forces
     • Most ionic substances ONLY dissolves in polar solvents. Non-polar molecules don't interact strongly enough with ions to pull them away from an ionic lattice.
       • The electrostatic forces between the ions are stronger than the bonds that can form between ions and non-polar solvent molecules
     • Most covalent substances ONLY dissolve in non-polar solvents. The inetrmolecular bonds are weaqk and can be broken by non-polar solvents molecules
       • Covalent bonds don't dissolve in polar solevtns. The hydrogen bonds are stronger than the bonds that would form between water molecules and intermolecular bonds.
   • Ionic solids dissolve in water
     • The H-O bonds are really polar and the ion-dipole bonds can be formed between the water molecules and the dissolved ions. The H is attracted to negative ions and the O is attracted to positive ions
