 Free energy of solvation
 Solvents are often refluxed with an appropriate desiccant prior to distillation to remove water. This may be performed prior to a chemical synthesis where water may interfere with the intended reaction

 Lyoluminescence
 Occupational health
 Partition coefficient (log P) is a measure of differential solubility of a compound in two solvents
 Solvation
 Solution
 Solvent systems exist outside the realm of ordinary organic solvents: Supercritical fluids, ionic liquids and deep eutectic solvents
