Question

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.
solution volume decreased
solute concentration decreased
solvent concentration decreased

Explanation:

Step1: Understand osmosis principle

Osmosis is the movement of solvent molecules from an area of higher solvent concentration (lower solute concentration) to an area of lower solvent concentration (higher solute concentration) across a semi - permeable membrane. In the U - shaped tube, water (solvent) will move.

Step2: Analyze volume change

The side with a higher solute concentration will draw in water from the other side. Since the right side has a higher solute concentration (more solute particles), water will move from the left side to the right side. So, the solution volume decreased on the left side.

Step3: Analyze solute concentration change

As water moves out of the left side, the solute concentration on the left side increases. As water moves into the right side, the solute concentration on the right side decreases.

Step4: Analyze solvent concentration change

As water moves out of the left side, the solvent (water) concentration on the left side decreases. As water moves into the right side, the solvent concentration on the right side increases.

Answer:

	Left side	Right side
Solute concentration decreased		X
Solvent concentration decreased	X
