Ion-Dipole Force
Definition: When one pole of a dipole is attracted to an oppositely charged ion. The
negative pole of a dipole will be attracted to a cation (positive charge) and the positive pole
of a dipole will be attracted to an anion (negative charge.)
Appears Between: Ions and Dipoles
Examples:
Water (H2O) and Dissolved Sodium Ion (Na+) in Sodium Chloride (NaCl) Solution
Water (H2O) and Dissolved Chloride Ion (Cl-) in Hydrogen Chloride (HCl) Solution
Water (H2O) and Dissolved Calcium (Ca) in Calcium Hydroxide (Ca(OH)2) Solution
Ion-Induced Dipole Interaction
Definition: When an ion approaches a molecule without a dipole and causes a
change in the distribution of charges to induce a dipole.
Appears Between: Ions and Non-polar Molecules
