Osmosis is often defined as the flow of water through a semipermeable membrane, from a dilute solution to a more concentrated solution.
Video experiment #1 – saturated sucrose/dialysis tubing/water osmosis from U Mich. https://youtu.be/pCupvFGN4bw
A saturated solution of sucrose-containing a red dye is separated from water by dialysis material.
What happens to the volume of sucrose solution during the experiment?
How do you know that the sucrose solution did not flow into the beaker of water? (Give evidence from your observation of the experiment.)
