Sastre de Vicente has recently published an excellent paper on the concept of ionic strength (1), detailing its empirical origin, its independent appearance in the theories of Debye and Hückel, its applications in solution chemistry and, most importantly, its interpretation as reflecting “the extent to which a potential difference induces a charge density difference”.
However, mention is not made of the recent unexpected appearance of an ionic strength factor in straightforward evaluations of the lattice energies of ionic solids, ranging from simple binary salts to complex minerals (2, 3). Reference to this novel activity has, however, appeared elsewhere in this Journal (4, 5). Such evaluations have opened a new arena in thermodynamic evaluation of solid-state processes (see, for example, refs 6 and 7, and references therein), which deserves to be made known to the wider educational community.
