Unformatted text preview: an area of lower solute concentration to an area of higher solute concentration (osmosis). When the water sacs are put into sugar beakers, the sac weighs less at the end. This can be explained by dialysis. Except for when there is an equal amount of sugar in the sac and in the beaker you will not expect to see any net movement of water. This is because the solution is isotonic to the solution in the sac....
