WebDissolving ionic compounds. When an ionic compound dissolves the ions in the giant lattice must separate and disperse into the solution. The large amount of lattice enthalpy needed to break the lattice is compensated by the hydration enthalpy of the ions and the increase in entropy in the disordered solution. WebLattice enthalpies calculated using Born-Haber cycles are experimental, because they use enthalpy changes that can be measured. Two factors that affect lattice enthalpy are the charge and the radius of the ions. Ions with large ionic charges have larger lattice dissociation enthalpies, because of stronger electrostatic attraction between the ions.
