If salt is added to oil, it will simply sink to the bottom of the container if it is denser, or float on top if it is less dense, remaining as a distinct solid. The polar nature of salt ions is incompatible with the non-polar structure of oil molecules.
Understanding Phase Separation in Salt and Oil Mixtures
Consequently, the salt remains intact as a separate phase. Summary of Key Concepts The inability of salt to dissolve in oil is a clear demonstration of the fundamental rules of chemistry.
For all practical purposes regarding food preparation and everyday chemistry, salt and oil remain immiscible. The Science of Solubility At its core, solubility is determined by the interaction between the solute—the substance being dissolved—and the solvent—the substance doing the dissolving.
Understanding Phase Separation in Salt and Oil Mixtures
Dissolving salt in water is effective because water molecules are polar and can surround and stabilize the individual sodium and chloride ions through ion-dipole interactions. The common observation of salt sitting on the surface of oil or remaining undissolved reveals a basic truth about molecular compatibility.
