Verified step by step guidance

Identify the concept of osmosis, which is the movement of solvent molecules through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration.

Understand that in a U-tube setup with a semipermeable membrane, the side with the higher solute concentration will draw more water from the side with distilled water, causing the liquid level to rise on the side with the solution.

Observe the images of the U-tubes provided. Each U-tube has a different height of liquid on the side with the solution (pink) compared to the side with distilled water (blue).

Compare the liquid levels in the left arm (solution side) of each U-tube. The U-tube with the highest liquid level on the solution side indicates the most concentrated solution, as it has drawn the most water from the distilled water side.

Determine which U-tube has the highest liquid level on the solution side, indicating the most concentrated LiF solution.
