When there is a semipermeable membrane separating two solutions of pure water, the two sides are at what state?
Correct Answer
equilibrium
Explanation
When a semipermeable membrane separates two solutions of pure water (equal concentrations on both sides), the two sides are at equilibrium. There is no net movement of water in either direction because the osmotic pressure is equal on both sides.
