Answer:

True

Explanation:

This process is called Chemiosmotic Theory.

Two different solutions with a semi-permeable barrier (it allows to pass throw just water or solute, not both) will try to get into equilibrium.

Then, if you allows to pass just water though the barrier, it will go from the solution with less solute to the solution with more solute, in order to reach the solution equilibrium.
