Solvent absorption

In chemistry, absorption is a physical or chemical phenomenon or a process in which atoms, molecules or ions enter some bulk phase – liquid or solid material. This is a different process from adsorption, since molecules undergoing absorption are taken up by the volume, not by the surface (as in the case for … See more If absorption is a physical process not accompanied by any other physical or chemical process, it usually follows the Nernst distribution law: "the ratio of concentrations of some solute species in two bulk … See more Absorption is a process that may be chemical (reactive) or physical (non-reactive).
