Question

the u - shaped tube model shows the effects of osmosis over time. u - shaped tube immediately after a different solution is added to each side u - shaped tube after time has passed decide whether each event happened on the left side or the right side of the u - shaped tube over time. complete the table. left side right side solute concentration decreased solvent concentration decreased solution volume decreased

Explanation:

Step1: Understand osmosis principle

Osmosis is the movement of solvent molecules from an area of high - solvent concentration (low solute concentration) to an area of low - solvent concentration (high solute concentration) across a semi - permeable membrane.

Step2: Analyze solute concentration change

In the U - shaped tube, water (solvent) moves from the left side to the right side because the right side has a higher solute concentration initially. As water moves to the right side, the solute concentration on the right side decreases. So, the solute concentration decreased on the right side.

Step3: Analyze solvent concentration change

Since water (solvent) moves from the left side to the right side, the solvent concentration decreases on the left side.

Step4: Analyze solution volume change

As water leaves the left side, the solution volume on the left side decreases.

Answer:

	Left side	Right side
Solvent concentration decreased	●
Solution volume decreased	●
