Osmosis when membrane is permeable to both solute and water?

  1. Jan 23, 2014 #1
    Hello everyone,

    Lets say there is a membrane, which has a channel for the solute(eg sodium) and another channel for water

    Now if I have a hypertonic (more sodium) solution in side A, and hypotonic (less sodium) solution in side B. Which way would water go?

    * I'm very confused here diffusion and osmosis both occuring.

    Does water follow sodium or sodium follows water?

    Thanks :smile:

    Do they have to go in the same direction?
