Hoff showed its namesake pressure, also known as turgor and defined as the applied stress required to cease it, is approximately colligative.
For a solute of mole fraction x [ecks], this ideally results in a chemical potential decrease of RT ln(1 – x) [arr tee times the natural log of one minus ecks]. Pfeffer made the first serious study of this spontaneous reaction in 1877 and van't Hoff showed its namesake pressure, also known as turgor and defined as the applied stress required to cease it, is approximately colligative. For 10 points, identify the diffusion process that is best defined as the spontaneous movement of water across a semi-permeable membrane.
For a solute of mole fraction x [ecks], this ideally results in a chemical potential decrease of RT ln(1 – x) [arr tee times the natural log of one minus ecks].
