Earlier I learned that osmosis was, like diffusion, a result of the laws of entropy, kinetic energy, and random movement. However, if you have two solutions of equal moles of water, then net movement should be zero, right?
In the case above with equal moles of water, if you now have a semi-permeable membrane (allowing only water molecules to cross) and solutes dissolved in the water (at difference concentrations), then there would still be net movement of water molecules towards the concentrated solution. There was an explanation in my AP Bio textbook that the water molecules hydrating the solutes were unable to pass through the membrane, so net movement occurs because of a difference in free water concentration.
Now I am just wondering what would occur if you had a nonpolar molecule instead of a solute. Would the arrangement simply remain at this?
