• The diagram shows a U-shaped tube containing solutions with different sugar concentrations separated by a selectively permeable membrane. What will happen if the solvent (water) can pass through the membrane but the solute (sugar) cannot?

• the concentration of sugar on the left will increase

• the concentration on the right will increase

• The diagram shows a U-shaped tube containing solutions with different sugar concentrations separated by a selectively permeable membrane. What will happen if the solvent (water) can pass through the membrane but the solute (sugar) cannot?

• the water will initially move from left to right

• the water will initially move from right to left
