When testing diffusion over a selectively permeable membrane, the proper setup is aimed at putting different concentrations into tubes and the same water volume.

<h3>What is a selectively permeable membrane?</h3>

A selectively permeable membrane is a physical barrier that allows the passage of certain substances but not others.

The cell membrane is a selectively permeable membrane that cells need to interchange nutrients and waste with their environment.

In conclusion, a suitable experiment to show the process of diffusion in a selectively permeable membrane is to put concentrations of the solute into tubes and the same volume of solvent (water).
