Abstract (EN): Computer simulations of salt solubility used a Java applet and Web browser to present an animated illustration of differences in the solubility of salts. The simulation provides an animated, visual interpretation of the different solubilities of related salts based on simple entropy changes associated with dissolution: configurational disorder and thermal disorder. Pairs of compounds chosen for the animation are NaCl/CaCO3 and MgCO3/MgSO4. In the former case, both dissolution are almost athermic, hence the major differences are in configurational disorder and solvation effects. In the latter pair, the major difference lies in thermal disorder, as the dissolution of magnesium sulfate is quite exothermic. Changes in total entropy and in its components are represented qualitatively in bar graphs.
