Question

If a 30% sucrose solution is separated from a 40% sucrose solution by a membrane impermeable to sucrose, in which direction will net movement of water occur?

Answer 1

Answer: from 30% sucrose solution to the 40% sucrose solution

Explanation:

From the definition of osmosis is the movement of water molecules through a selectively permeable membrane from a region of lower solute into a region of higher solute concentration, until the solute concentrations on the two sides is equal.

Therefore the net movement of water molecules will move from 30% sucrose solution to the 40% sucrose solution until the concentration of sucrose on both sides of the impermeable membrane is equal 35% each.
