This can be calculated using the radii and charges of all the ions involved in the Kaputinskii equation.  
This can be calculated using the radii and charges of all the ions involved in the Kaputinskii equation.  Other methods include a derivative of Coulomb's law and the most common method, the Born-Haber cycle, but all methods of calculating it are approximations.  In order for dissolution to occur, the new intermolecular forces created must compensate for this quantity.  The similar quantity for the reverse process is the energy of crystallization.  Measured in kJ/mol, FTP, name this quantity with symbol U, the energy required to separate an ionic solid into gaseous ions.          |
