Hi all,
In osmosis a solvent moves across a semi-permeable membrane when the solvent is on both sides of the membrane but the concentration of the solute differs. Normally solvent moves from the side with high osmotic pressure (solvent containing less solute) to side containing more solute. However if one side of the membrane contained a solution and the other side was just air would the solvent move through the membrane to the air side by diffusion? If it did then immediately the solvent that passed through which would not not contain solute would move back to the side with higher solute concentration due to osmosis? If no water would move across why not?
