An imbalance of solute concentration across a semi-permeable membrane initiates the transport of water from the region with lower solute concentration towards the region with higher solute concentration. This movement of water is known as osmosis.
When the solute concentration inside the balloon (20%) is lower than outside (40%) it, water would tend to move out of the balloon into the solution in the beaker.
In the lab, you use a special balloon that is permeable to water but not sucrose to make an "artificial cell." The balloon is filled with a solution of 20% sucrose and 80% water and is immersed in a beaker containing a solution of 40% sucrose and 60% water. The solution in the balloon is ______ relative to the solution in the beaker.
