The ionic strength of a solution is a measure of the concentration of ions in that solution. Ionic compounds, when dissolved in water, dissociate into ions. The total electrolyte concentration in solution will affect important properties such as the dissociation constant or the solubility of different salts. One of the main characteristics of a solution with dissolved ions is the ionic strength. Ionic strength can be molar (mol/L solution) or molal (mol/kg solvent) and to avoid confusion the units s… WebThe Born-Haber cycle is an application of Hess’s law that breaks down the formation of an ionic solid into a series of individual steps: ΔH ∘ f, the standard enthalpy of formation of the compound. IE, the ionization energy of the metal. EA, the electron affinity of the nonmetal. ΔH ∘ s, the enthalpy of sublimation of the metal.
