Negative solvent pressure in osmosis: A Gedanken experiment

  • Henry R. Hirsch


A hypothetical experiment illustrates the relationship between the chemical potential of a solvent in a solution and the partial pressures of the solvent and solute. Hydrostatic and osmotic pressure differences which produce equal transmembrane solvent flows are compared. Results indicate that chemical-potential and partial-pressure descriptions of a solution are both consistent with the concept of a negative absolute solvent pressure.
