Osmosis
Historical document, translated for reference. It reflects medical knowledge of the 1920s–30s and is not medical advice.
Summary
This 1930s encyclopedia article defines osmosis as the movement of a solvent through a semipermeable membrane toward the solution with a higher concentration of solute and greater osmotic pressure. It also notes that fluid movement through porous membranes can occur under the influence of electrical forces.
Encyclopedia entry (1928–1936)
OSMOSIS, the movement of a solvent through a semipermeable membrane that completely or partially retains dissolved substances. Osmosis occurs through the membrane toward the liquid in which the dissolved substances retained by the semipermeable membrane are present in a higher concentration and, accordingly, produce a greater osmotic pressure (see). The movement of liquid through porous partitions can also occur under the action of electrical forces (see Electro-osmosis).
