A 10% glucose solution is placed in the thistle tube. The thistle tube is placed in a beaker that contains a 5% glucose solution. There is a differentially permeable membrane across the broad end of the tube, which is permeable to water but not to the sugar glucose. What will occur over time to the water? To the solute?

Respuesta :

The water from the 5% glucose solution will flow into the 10% one, as water molecules will flow from a region of high water potential (dilute solution) to a region of lower water potential (concentrated solution) by osmosis.
Osmosis only occurs when a differntially membrane exist, and its only about the net movement of water particles.
Therfore the result would be the water volume in the 10% glucose would rise, and the solute in the original 10% one would be less concentrated, while originally in the 5% one would be more concentrated.
