Semi-permeable diffusion questions

  1. Sep 12, 2006 #1

    I'm having some trouble understanding semipermeable diffusion questions. Does anyone know of a good book or web source with examples?

    Also, if anyone could help me out on these...

    What is the equilibrium situation?

    Left side has90 mM KCL and right side has 20 mM KCl. Membrane in between is permeable to both, with a greater permeability to Cl. Impermeable to water.

    Left side is 50 mM glucose, 10mM mannitol. Right side is 20 mM glocose, 20 mM mannitol. Membrane permeable to glucose and water; impermeable to mannitol.

    Left side is 5 mM LiCl and 90 mM sucrose. Right side is 50 mM LiCl. Membrane is permeable to Li and water; impermeable to sucrose and Cl.
