57. Answer is d. less concentrated since water passes from B to A.

Osmosis is the movement of water molecules from a region of higher water concentration to a region of lower water concentration. So water will move from B to A, making it less concentrated solution.

An important part to notice here is that its the movement of water molecules (or any other solvent) through the membrane and not the particles dissolved in the water.

58. Answer is a. It will rise in side A since water (not the substance in it) will tend to pass from the area of greater concentration to the area of lesser concentration.

Answer:

Part 1.

The option A is correct.

Explanation:

• As the solution A is hypertonic as compared to solution B. So water will move from B to A by the process of osmosis.

• Osmosis is the movement of water or other solvent through a plasma membrane or semipermeable membrane from a region of low solute concentration to a region of high solute concentration.

• Osmosis is passive transport, meaning it does not require energy to be applied.


Part 2.

The option A is correct one.

Water level rises in A side tube.

Explanation:

• Because the solution A is hypertonic as compared to solution B. So water will move from B to A by the process of osmosis.
