Consider the system at the point when it has reached equilibrium. The condition for this is that the chemical potential of the solvent (since only it is free to flow toward equilibrium) on both sides of the membrane is equal. The compartment containing the pure solvent has a chemical potential of , where is the pressure. On the other side, in the compartment containing the solute, the chemical potential of the solvent depends on the mole fraction of the solvent, . Besides, this compartment c… WebThese are the possible components of the water-potential equation: Osmotic Potential refers to the energy needed to create an equilibrium between solution and pure water separated through a semipermeable membrane.
