WILL MEDAL AND FAN!!!
The figure shows a classic experiment that demonstrates the principle of osmosis.

The left side of the U-tube is filled half-way with 10% red sugar water. Into the tube on the right, distilled water is poured until it is even with the red sugar water. A semi-permeable membrane is placed in the brown area. Predict what will happen in the U-tube after several hours.

A. The membrane in the middle will melt away and both sides will mix

B. Both sides will become 5% red sugar water and willl be at equal marks on the YouTube given enough time.

C. The left side of the tube will remain red as the right side of the tube falls in volume. The distilled water will dilute the sugar water.

D. The left side of the tube will remain red, but will fall. The right side will remain clear, but will rise, as water moves from the 10% sugar water to the distilled water.

Answer 1

which way does water move? toward a high concentration or solute, or low? and can sugar pass the semipermeable membrane?

Answer 2

oops, *of solute, not or

Answer 3

Water moves to balance the concentrations of solvents across a membrane (assuming the salt cannot pass through the membrane) then the water would move from low salt concentration to high, to even the concentrations across the membrane. C, if the membrane does not allow salt through.
