Question

osmosis across a cell membrane can be modeled using a u - shaped tube. this diagram of a u - shaped tube shows two solutions immediately after they were poured into the tube. the solutions were made by dissolving different amounts of the same solute in water. according to the diagram, which statements describe the solutions immediately after they were poured into the u - shaped tube? select all that apply. the two solutions are at equilibrium. the two solutions have the same concentration. water is the solvent in both solutions. the two solutions have the same volume.

Explanation:

1. The diagram shows two solutions with different solute - to - water ratios initially, so they are not at equilibrium.
2. The solute concentrations are different as different amounts of solute are dissolved in water.
3. It is stated that the solutions are made by dissolving solute in water, so water is the solvent in both.
4. The U - shaped tube has equal - height columns of the two solutions, indicating the same volume.

Answer:

C. Water is the solvent in both solutions.
D. The two solutions have the same volume.
