Question

If more sugar were added to the solution on the left side of the tube, what would happen to the water level on the right side of the tube?

Answer 1

The given question is incomplete. The complete question is as follows.

If more sugar were added to the solution on the left side of the tube, what would happen to the water level on the right side of the tube?

• There is more solute in the left arm of the tube than in the right arm of the tube.

• There is less free water in the right arm of the tube than in the left arm of the tube.

• Water is tightly clustered around the hydrophilic solute molecules on both sides of the membrane.
• Solutes can pass through the selectively permeable membrane from right to left, but free water cannot.

Explanation:

It is known that when water is able to diffuse through a semi-permeable membrane from a region of high water concentration to low water concentration is called osmosis.

Since, more amount of solute is present on the right side of the tube so, there will be less amount of free water present over there as compared to the left side of the tube.

Also, water will be clustered around the hydrophilic solute molecules which is present on both sides of the membrane.

Thus, we can conclude that the true statements are as follows.

• There is less free water in the right arm of the tube than in the left arm of the tube.

• Water is tightly clustered around the hydrophilic solute molecules on both sides of the membrane.
