The figure shows a classic experiment that demonstrates the principle of osmosis. The left side of the U-tube is filled half-way with 10% red sugar water. Into the tube on the right, distilled water is poured until it is even with the red sugar water. A semi-permeable membrane is placed in the brown area. Predict what will happen in the U-tube after several hours.
A) The membrane in the middle will melt away and both sides will mix.
B) Both sides will become 5% red sugar water, and will be at equal marks on the U-tube given enough time.
C) The left side of the tube will remain red, but rise in volume, as the right side of the tube falls in volume. The distilled water will dilute the sugar water.
D) The left side will remain red, but it will fall. The right side will remain clear, but it will rise, as water moves from the 10% sugar water to the distilled water.

The left side of the tube will remain red, but rise in volume, as the right side of the tube falls in volume. The distilled water will dilute the sugar water.

Out of the provided options, the left side of the tube will remain red. However, there would be an increase in the volume as the right side of the tube drops in volume. The distilled water will also dilute the sugar water.

Further Explanation:

Osmosis refers to the spontaneous movement of the solvent particles via a semi-permeable membrane from a lower to the higher region of concentration, in the direction which tends to maintain equilibrium onto both sides. This process is essential in the biological systems as the membranes are semi-permeable.

In the given experiment, there are two tubes wherein one of them is filled with red sugar water while the other one is filled with distilled water and is segregated with a semi-permeable membrane. Osmosis will always focus on maintaining the equilibrium on both sides.

During this experiment, the solvent molecules will flow from lower to higher concentration region, which means that the molecules will move from the distilled water towards the sugar water. This will result in an increase in the volume of the left tube whereas there will a drop in the volume in the right tube. The distilled water will dilute the sugar water as the molecules move out.
