The dissolution of a solid can be thought of as occurring in three hypothetical steps: (1) the breaking apart of the solid, (2) the spreading out of the solvent, and (3) the interaction of the dissolved solid with the solvent. As shown in this video, we can predict the signs of the enthalpy and entropy changes for each of these steps and relate this information to the solubility of the solid.
