Question

A student experiments with two solutions containing the same solute concentrations

in a beaker that is divided by a semipermeable membrane, as shown.
left
right
semipermeable membrane
In which direction will the water move so that the concentrations of the solutions
remain constant on both sides of the membrane?
A in both directions at different rates
B in both directions at the same rates
C toward the right side of the beaker
D toward the left side of the beaker

Answer 1

When solutions of different osmolarities are separated by a membrane permeable to water, but not to solute, water will move from the side with lower osmolarity
