Final answer:
After osmotic equilibrium is reached, water will no longer flow across the semipermeable membrane.
Step-by-step explanation:
After osmotic equilibrium is reached, water will no longer flow across the semipermeable membrane. Osmotic equilibrium is achieved when the solute concentrations on both sides of the membrane are the same. At this point, there is no concentration gradient to drive the movement of water, so the flow stops.
