Abstract
THE molar volume change on fusion of an ionic compound, ΔVfusion, is relatively easy to determine. It may be found directly, by observing the change in length of a column of fused salt in a capillary when this is cooled through the freezing temperature, or indirectly by measuring the freezing point of the salt as a function of pressure and applying the Clapeyron–Clausius equation. The literature now contains reliable values of ΔVfusion for the common inorganic salts1,2.
