Question

When solvent molecules selectively pass through a membrane from a dilute solution to concentrated solution, what process is occurring?

Answer 1

osmosis

 a  Two solutions of differing concentrations are placed on either side of a semipermeable membrane.  b  When osmosis occurs, solvent molecules selectively pass through the membrane from the dilute solution to the concentrated solution, diluting it until the two concentrations are the same. The pressure exerted by the different height of the solution on the right is called the osmotic pressure. The osmotic pressure of a solution is easy to calculate:.
