Lösungsmittelvorgängen

Lösungsmittelvorgängen, also known as solvent processes, refers to the phenomena and interactions that occur when a substance, the solute, dissolves in another substance, the solvent. This process involves the breaking of intermolecular forces within both the solute and the solvent, and the formation of new intermolecular forces between the solute and solvent particles. The ability of a solvent to dissolve a solute is influenced by several factors, including the polarity of both substances. Generally, "like dissolves like," meaning polar solvents tend to dissolve polar solutes, and nonpolar solvents tend to dissolve nonpolar solutes.

The dissolution process can be endothermic, exothermic, or thermoneutral, depending on the relative strengths of the forces being broken and formed. When a solute dissolves, it becomes solvated by the solvent molecules. In the specific case where the solvent is water, this process is called hydration. Solvent processes are fundamental to many chemical and biological systems, including chemical reactions, extraction, chromatography, and the transport of substances within living organisms. Understanding these processes is crucial for fields ranging from chemistry and materials science to pharmacology and environmental science. The rate of dissolution is affected by factors such as temperature, surface area of the solute, and agitation.
