The Role of Energy in the Process From an energy perspective, dissolving a substance is a process that involves breaking and forming attractions. The Science of Solubility: "Like Dissolves Like" The foundational rule governing whether one substance will dissolve in another is often summarized as "like dissolves like.
Energy Perspective on Mixing Salt and Oil
If you add table salt to a bottle of cooking oil and shake it vigorously, the salt will appear to dissolve momentarily. When these interactions are energetically favorable, dissolution occurs; when they are not, the substances remain distinct.
This separation is so reliable that oil-based methods are actually used to extinguish certain types of grease fires, as the water-based salt solution can be effectively separated from the fuel source. The weak London dispersion forces holding oil molecules together are insufficient to overcome the strong ionic bonds in salt, and more importantly, there is no favorable interaction between the charged ions and the neutral oil molecules.
Energy Perspective: Understanding Salt and Oil Mixing
This is not true dissolution but rather a temporary suspension of solid particles. When introduced to a polar solvent like water, the surrounding water molecules effectively pull these ions apart through ion-dipole interactions, leading to dissolution.
